The Senegalese striker has been attracting interest from a host of clubs after his impressive form so far this season and Arsenal are reportedly in pole position to secure his signature.

The former West Ham United front man even went as far as saying the north London club are "one of these teams who make you dream", fuelling speculation he is looking for a move away from Newcastle.

However, Wenger has attempted to quell the speculation over a possible bid for Ba by publicly stating that he is not looking to sign the striker.

"It is not right to speak about him because he plays against us tomorrow," he told reporters ahead of Newcastle's visit to Arsenal on Saturday.

"If you ask 'do we sign him?' I say no."

Wenger refrained from speaking about any potential signings as he looks to improve his team who, sit seventh in the English Premier League.

He did not rule out a possible third spell at the club for Thierry Henry, who has reportedly already agreed to join the club on loan.

"Any interest we have in any player has to be kept secret so I cannot come out with any names," Wenger said.

"I have not lost interest in him (Henry), he is still coming today to practise with us. I have not ruled out a move completely."

Wenger also questioned the decision of referee Mike Dean not to send Manchester United manager Alex Ferguson to the stands after his touchline tirade in a 4-3 win over Newcastle on Wednesday.

"Why should anybody be scared of Ferguson? I don't understand that," he said when quizzed on alleged reluctance of referees and the Football Association to discipline the United manager.

"I think you have the rules and you can observe them or not and referees have to act on that.

"They are professional people, they are paid for that. It's as simple as that. On the day they made a mistake, that doesn't mean that they are not honest, but they made a mistake."
