Jack Wilshere shines amid the gloom as Arsenal struggle for midfield creativity in 2-0 victory over West Brom Wilshere's understanding with Mikel Arteta and Santi Cazorla also continues to develop and, during the second half, they produced one breathtaking sequence of passing that was reminiscent of Arsenal at their fluent best. Wenger acknowledged that he now faces a dilemma over whether to stick to his plan of giving Wilshere "a breather" every third or fourth game. "I have still to be cautious but, when he plays at that level and you are under the pressure we are under to win the games, it is difficult to leave him out," said Wenger. Wilshere rated himself at "90 per cent" but admitted that it was his best performance since coming back. "When I get up to 100 per cent I will really show what I can do," he said. Questions do persist, however, about Arsenal's cutting edge and they still had to be reliant on two fortuitous penalties, converted by Arteta, to make their dominance count. Wenger rightly wants to shake up his attacking options in January and, with a loan for Thierry Henry now almost complete, bids can be expected for Schalke's Klaas-Jan Huntelaar and Crystal Palace winger Wilfried Zaha. Steve Clarke, the West Brom manager, understandably highlighted refereeing errors, notably for Cazorla's dive, but should be equally unhappy with a team performance of such limited attacking ambition.
