Edson Alvarez has admitted his frustration with Ajax after being blocked from joining Chelsea on deadline day this season.
The Blues came in for him over the summer and the Eredivisie side rejected the move.
This upset Alvarez, who has also been the subject of interest from Barcelona and Manchester United, and he hit out at Ajax suggesting are not a big club.
He told ESPN: "I am very disappointed about it. But I am convinced that one day a big club will come.
"We never expected Chelsea to put in another bid at the end of August. It was a difficult situation.
"They [Ajax] didn't have a player in my position. Of course I fought as far as I could [to leave]. I didn't want to do that too much.
"Because I know the responsibility I have within the club. Ajax couldn't do anything."
