Elsewhere, Arsenal manager Arsene Wenger has criticised Mark Hughes' defence of Emmanuel Adebayor in the escalating row over the conduct of the Manchester City striker.
The Togo striker has found himself in the spotlight following his erratic behaviour during Saturday's 4-2 victory over former club Arsenal.
Adebayor ran the full length of the pitch to celebrate scoring in front of travelling Gunners fans, which led to a steward being injured.
He then left former team-mate Robin van Persie with a gashed face after a challenge which the Dutch striker described as a 'mindless and malicious stamp'.
Adebayor is facing Football Association charges of both violent and improper conduct and could be handed anything up to a six-match ban.
But Wenger has chosen to speak out after being riled by City boss Hughes' defence of the striker he paid £25million for during the summer.
