The introduction of Cesc Fabregas against Aston Villa yesterday swung the game in Arsenal´s favour, despite the influential Spaniard only being on the field for 28 minutes.

Two sublime goals added to a third from the improving Abou Diaby ensured a precious three points for Arsenal in their title challenge. However, it came at a cost with both Fabregas and Denilson picking up knocks which could see them miss Wednesday´s trip to Portsmouth and possibly longer.

With Alex Song set to travel to the African Cup of Nations shortly, options are considerably low in midfield. One possible option could be for Aaron Ramsey to start against Pompey, the side who he scored his first Premier League goal against back in September.

Ramsey replaced Fabregas yesterday and struggled to settle into the game but his improvement has been notable this season. He has resembled Fabregas at times when playing for Wales and, if he can cope with the physical nature of the Premier League, something he should be used to having played rugby when he was younger, then this could be a big period in the Welshman´s season.

Wenger hinted at buying a midfielder after yesterday´s game and it is obvious why he feels his side are short in that area when shorn of three important individuals. Ramsey, however, who can operate either in the holding role or Fabregas´position, will be determined to prove otherwise.
