Former Arsenal defender William Gallas has admitted that it may be the right time for the club to replace manager Arsene Wenger come the end of the season.
The French coach has not yet signed a new contract, prompting rumours that his 21-year spell at the club could come to an end.
And Gallas hasexpressed his beliefthat Arsenal - who have not won the Premier League since 2004 -must 'find a solution.'
Maybe it is time to change something at the end of the season," he toldtalkSPORT."We can't forget what he did for the club. He did a very, very good job so sometimes you can't sack the manager like this. You have to respect the manager.
"That is why I said at the end of the season maybe the board has to speak with Arsene and try to find a solution."
Gallas also made a comparison between Wenger and Jose Mourinho, claiming that the latteris more focussed on success.
"You get criticism when you don't win trophies, when you don't win games, and that is maybe the difference between Jose Mourinho and Arsene Wenger," he added.
"Mourinho wants to win every game and at the end of the season sometimes he has success but, for Arsene, Arsenal didn't win from 2004 so everybody starts to criticise him because football has changed.
"Football is about victory, about trophies. Players want to lift trophies. If you don't lift a trophy in your career, you will feel disappointed at the end of your career.
"I don't know what Arsenal are going to do but they have to win trophies again.�
