Keown: Arsenal must shut up Mourinho

Former  Arsenal  defender Martin Keown insists that  Arsene Wenger  's men cannot afford to lose this weekend's Premier League showdown against  Chelsea  if they are to keep  Jose Mourinho  quiet.

 Mourinho and Wenger have developed a frosty relationship over the years and Keown fears the Chelsea boss will publicly criticise his Arsenal counterpart once more if he emerges victorious on Saturday, like he did in February 2014 when he branded the Frenchman a "specialist in failure".

 Champions Chelsea sit fourth bottom in the Premier League after taking just four points from their opening five games, while Arsenal suffered a surprise 2-1 Champions League defeat at Dinamo Zagreb in midweek, and Keown believes that the confidence of both teams is "brittle" heading into the clash.

 "Chelsea will feel that they are bouncing back - suddenly this has become a different game for Arsenal," he told the  Daily Mail  .

 "It's then how they apply themselves. They got a drubbing in early kick-offs at Anfield and Chelsea, and there can't be any hangover even though they'll come back late from Zagreb.

 "Mourinho's team will start like a house on fire. Victory rescues their season.

 "Arsenal don't want Mourinho talking afterwards about how special he is again and how Arsenal have failed again.

 "Wenger needs to create that urgency that their season hinges on this match."

 Arsenal beat Chelsea 1-0 earlier this season to win the Community Shield.
