Tottenham head coach Martin Jol has called striker Mido "irresponsible and disrespectful" for comments about former Spurs hero Sol Campbell.
Mido has incurred Jol's anger over his comments
Speaking ahead of Sunday's match against Portsmouth, Mido said Campbell was "one of the easiest defenders" he had played against.
Jol said: "I have told him to let his football do the talking in the future."
Portsmouth coach Harry Redknapp said Mido's comments were "arrogant" and "an insult" to the 32-year-old defender.
Campbell is certain of a hostile reception from Tottenham fans in Sunday's match at White Hart Lane following the former England defender's move to Spurs' bitter rivals Arsenal in July 2001.
"Given the feelings that still run high about Sol among our supporters, Mido's comments were not only disrespectful, they were also irresponsible," Jol added.
I won't have to say too much to my lads in the dressing room - I'll just stick a newspaper cutting up on the wall
Campbell has played in all six of Portsmouth's league matches this season, during which the team has only conceded one goal.
He was backed by Pompey boss Redknapp who said: "Those comments will embarrass every footballer in the game as we don't talk like that about fellow pros.
"I'm sure his manager at Tottenham will also be embarrassed when he reads those remarks as it shows Mido has no real feeling for the game over here.
"One thing is for certain, I won't have to say too much to my lads in the dressing room at Tottenham.
"I'll just stick a newspaper cutting up on the wall and that will do for me."
