Expectations indicate that the summer transfer period will be the most exciting in many years, with important options for some players against the likes of Sergio Ramos, Erling Haaland, Kylian Mbappe and Harry Kane, as well as Lionel Messi.

There are 20 decisions that will have an earthquake impact on the summer transfer market:

Messi series

This decision is around the corner, with Messi's contract expiring at the end of this month.

Barcelona knows that their entire project under the leadership of "Barca" president Joan Laporta, depends on his decision to stay in the "Camp Nou" or leave.

At the moment, everything points to its renewal.

"Messi's situation is going well, but it's not over yet," Laporta said.

Mbappe continues to dribble

Mbappe's future appears to have dominated the headlines all summer.

The 22-year-old has a contract with Paris Saint-Germain until the summer of 2022, but renewal talks with his club have not started and Real Madrid is waiting in the wings.

The player's market value is 160 million euros, so his transfer will have a seismic effect on the transfer market.

Cristiano puzzle

Cristiano Ronaldo may be looking for a way out of Juventus after a difficult season.

Although he finished the season as the top scorer in the Italian Serie A, his team failed to win the title, which frustrated the player.

But Juventus snatched one of the qualifying spots for the Champions League at the end of the season.

After 3 years in Turin, the Portuguese star may want to leave and look for a new challenge or return to an old team.

Haaland Bank

There is no world football team that would not want to include Norwegian top scorer Erling Haaland, given his incredible ability and potential.

He is not expected to stay in Borussia Dortmund until the end of his contract in 2024, and despite the many offers and those wishing to include him, his future destination will not be decided yet and when it will be next season or the next.

Griezmann effect

The French career Antoine Griezmann - which lasted two years in the "Camp Nou" - suffered from lack of continuity and sub-par performance.

With his contract expiring in 2024, Barcelona are looking to sell him this summer, and it can be guaranteed that there are many willing to sign him.

Bad luck Hazard

The status of Belgian Eden Hazard is one of the most talked about mysteries in European football.

The excitement about his arrival in the summer of 2019 quickly faded after a serious ankle injury he suffered in the Champions League against Saint-Germain.

He has struggled since his return as his market value has fallen, and Real are looking to sell him this summer.

Harry Kane surprise

While England striker Harry Kane is desperate to leave Tottenham this summer, the status of his contract could make the move difficult.

His contract runs until 2024, and any club wishing to sign him must pay more than 100 million euros.

Dembele history

After arriving in Barcelona with the task of filling the void of Brazilian star Neymar, the return of Frenchman Ousmane Dembele was largely disappointing, although he had his best season in the "Camp Nou" last summer.

His contract expires in the summer of 2022, but talks to extend his contract may lead to his departure this summer.

Sergio Ramos time

Real Madrid captain Sergio Ramos is facing a difficult summer, with his contract expiring in a few weeks and the club unwilling to give him a long-term contract, and he is also not wanted by other major European clubs.

Donnarumma slap

Italian goalkeeper Gianluigi Donnarumma faces an uncertain summer.

After announcing his departure from Milan, it does not appear that he is close to moving to a big club.

Meanwhile, the Rossoneri have already signed French former Lille goalkeeper Mike Minigne.

Doubt about Dybala

Argentine Paulo Dybala found his career stuck in limbo, with the expiration of his contract with Juventus in the summer of 2022 and the lack of agreement to extend his contract.

And it looks like he's ready to leave the club this summer.

And at the age of 27, he will surely have a major role with any team he signs with.

Bill's dilemma

The situation with Welshman Gareth Bale is more unpredictable than ever.

He is supposed to return to Real this summer, and there is news that he will retire after the end of the European Nations to be held in a few days, but his agent denied these "rumours".

Joao Felix District

Although it seemed certain that he would stay at Atletico Madrid after winning the La Liga title, the possibility exists that Portuguese Joao Felix will leave this summer.

The 21-year-old's contract runs until 2026, but this season he has shown that he is not a vital Rojiblancos player.

Varane and open possibilities

With his contract expiring next summer, French central defender Raphael Varane appears likely to leave Real this summer.

More than one major European team has expressed its desire to sign the 28-year-old, and his club is looking to secure large transfer fees.

Classic Lautaro

Argentine Lautaro Martinez has become a key player every transfer window.

After winning the Serie A title with Inter, he could be on his way this summer to leave this country, with Barcelona, ​​Atletico and Real Madrid all interested in the 23-year-old.

Morata.. another summer 

The future of Argentine Alvaro Morata is unclear.

While Juventus have the option to sign him permanently from Atletico Madrid, it is not known if he will stay in Turin or return to Atletico as his contract expires in the summer of 2023.

Jadon Sancho the Magician

England's Jadon Sancho - the Londoner who dribble like the Brazilian - may be on his way out this summer.

However, any move would be complicated by Borussia Dortmund's desire to keep Sancho and Haaland with him.

Condi Treasure

Heavy-caliber battles are being waged by the big European teams to win the services of French defender Jules Conde, who plays for Seville, who is considered one of the best midfielders in world football.

His market value is 80 million euros, but it's not out of the price range for many clubs, and he could be on his way out of Sevilla this summer.

Wijnaldum and the free deal

Liverpool are preparing to lose Dutchman Georginio Wijnaldum, who has been a vital player in their success in recent seasons.

After his transfer to Barcelona was guaranteed, Saint-Germain entered the line and offered the player double the wages he would have received from Barca, and they signed a contract until 2024.

Depay's latest episodes

With his contract expiring this summer, 27-year-old Dutchman Memphis Depay seems likely to move to Barcelona.

No wonder his compatriot, Ronald Koeman, coach of "Barca", was keen to bring him to the Camp Nou.
