Dick Advocaat took a hard look at the KNVB at his press conference on Friday.

The 73-year-old coach of Feyenoord finds it incomprehensible that referee Siemen Mulder was in charge of the lost cup match against sc Heerenveen (4-3) on Wednesday.

"I don't understand that we first got Björn Kuipers as referee for such a big quarter-final match and then - with all due respect - we got a much less referee", said an irritated lawyer.

"There were twelve men abroad and for such a big match we didn't get Kuipers, Makkelie or whatever they are called in return. I find that disturbing. I didn't think this referee whistled his best match."

Kuipers was initially appointed to whistle in the game between Heerenveen and Feyenoord on February 12, but that cup match was canceled due to weather conditions.

Because Kuipers was in charge of FC Barcelona-Paris Saint-Germain on Tuesday, he was replaced by Siemen Mulder in the make-up game on Wednesday.

Mulder claimed a leading role on Wednesday by sending Steven Berghuis off the field with two yellow cards and giving Heerenveen a questionable penalty kick.

Feyenoord gave away a 1-3 lead in the final phase and eventually lost 4-3.

Possible goalkeeper problem for Feyenoord

Lawyer may have a goalkeeper problem before the game with FC Twente on Sunday.

Both Nick Marsman and Justin Bijlow are not fit and may not be available against the Tukkers.

23-year-old Bijlow recently returned after a long injury, but was injured again a week ago.

On Wednesday he could not participate in Friesland either.

Marsman, who left a great impression earlier this season as a replacement for Bijlow, played an unfortunate game on Wednesday and therefore did not come out of the fight unscathed.

If both keepers are not available, third goalkeeper Ramón ten Hove will probably make his debut.

Goalkeepers Justin Bijlow and Nick Marsman have doubts about the away match against FC Twente.

Lawyer: 'All excuses are gone'

Due to the elimination in the cup, Feyenoord is only active in the competition.

"All apologies are gone, we have to show it now", continues Advocaat, who sees the season as successful when Feyenoord gets European football.

"Many people have already made their judgment, but the season is far from over. The moment now is not decisive, what happens in three months will be decisive.

The game between FC Twente and Feyenoord starts on Sunday at 2.30 p.m. and is led by referee Danny Makkelie.
