Arsenal boss Arsene Wenger says their Champions League victory over AZ Alkmaar is proof enough that they do not need to buy in January.

Wenger's men defeated their Dutch opponents 4-1 at the Emirates Stadium to leave them needing a point to qualify for the Champions League knockout stages.

Cesc Fabregas opened the scoring with a tame effort that beat goalkeeper Sergio Romero before Andrey Arshavin took centre stage, setting up Samir Nasri, Fabregas again and Abou Diaby.

Assessing the number of attacking options in his squad, Wenger said: "As many on the creative side? Certainly not. We had still Nicklas Bendtner and Theo Walcott who are offensive players who are not available.

"Denilson, Eduardo, Rosicky did not start, that is why I was amazed when people said 'buy, buy, buy.' And Vela as well, I forgot him."
