The game sees the in-form Wales international return to the club where he began his career and as the Gunners' leading scorer this season with 11 goals.

“At Swansea he got stick, at Cardiff I don’t know,” the Frenchman told reporters.
“I think the first time he went back there in the Cup tie he was not comfortable with the situation - it was too much for him. Now he is much more experienced.
“At Swansea it inspired him. The first time it affected him, now he takes that in a more positive way.
“He wanted to do so well that he missed a lot of passes at Cardiff. Every time he has come back to Wales since he has done well.
“I don’t think he will get a hostile reception, not at Cardiff, I don’t think he will. He got a hostile reception at Swansea because, like everywhere in the world, Swansea hates Cardiff and Cardiff hates Swansea.”
Despite the blistering start to the season which has seen Ramsey fire his side to the top of the Premier League table, Wenger insists he can still improve further.
“I expect him to continue to improve,” he added. “He’s a young player and of course there is a lot more to come from him.
“He has no limitations in his improvement and he can be a complete midfielder, efficient defensively, efficient offensively. That’s what real football players are.”
Cardiff have already beaten Manchester City at home this season and grabbed a point against champions United last time out with a late goal and Wenger is aware his side face a tough test.
“We have the warning of the performances they put in against the big teams,” he continued.
“So we are in a position where we have a difficult challenge but as well a very exciting challenge because we must do better than the other teams to get a result.”
