Werder Bremen midfielder Davy Klaassen has taken fresh aim at former Everton boss Sam Allardyce.

Signed by Ronald Koeman at Everton, Klaassen never got along with his successor, Allardyce.

"I only talked to him in his office three times.

"And at some point I realized: No matter what I say, he does not care," rapped the Dutchman to Voetbal International.

Klaassen managed only three appearances under Allardyce.
