Harry Redknapp has been warned over his future conduct following his post-match comments about the performance of referee Chris Foy during Tottenham's defeat at Stoke.
The Spurs boss said he felt like Foy "was quite enjoying not giving us anything" during the 2-1 defeat on Sunday.
The Football Association looked at the comments but decided against taking disciplinary reaction and instead have written to Redknapp.
An FA spokesman said: "We have written to Harry Redknapp following his post-match comments on Sunday warning him as to his future conduct."
Redknapp claimed refereeing decisions cost his side after Spurs had a goal disallowed, two penalty appeals for handball turned down, and had Younes Kaboul red-carded.
He said after the game: "To be honest, from the start of the game I felt like he wasn't going to give us much today. I just felt like he was quite enjoying not giving us anything.
"He's not made mistakes because he meant to, he is an honest guy, but today I just felt he had a bad day, and so did the linesman who missed [Emmanuel] Adebayor being two yards onside.
"He'll look at it tonight, on TV, when his wife is making him a bacon sandwich and think, 'Oh **** me, what have I done there?"'
