Santi Cazorla and Aaron Ramsey

Arsenal have received a major boost in the form of Aaron Ramsey, who has returned to full training after being out for over three months with a thigh injury.

Arsene Wenger has revealed that the player is in contention to play against Everton on Sunday but is likely to make the bench given the length of the layoff.

The Welshman has been Arsenal's standout player this season, scoring eight goals in the league and has been central to the Gunners' first-half charge this season. The 23-year-old suffered a thigh strain against West Ham in December and has not been able to play since, something that has had an impact on Arsenal's results thus far.

Ramsey's work rate and runs from midfield have been a major asset for Arsenal, who have been top of the league for major part of this season.

However, injuries to Theo Walcott and the Welshman cut their form short as they struggled to get past tough opposition and were humiliated by the likes of Liverpool and Chelsea in the past two months.

Arsenal fans will be happy that they have Ramsey back at a crucial part of the season, with Everton closing in on the Gunners and with the FA Cup semi-final with Wigan scheduled next week at Wembley.

Nacho Monreal is also likely to be available for the clash, which should give the Gunners some much needed back-up at left-back, with Laurent Koscielny not expected to be back until next week.

"Aaron and Nacho Monreal are back training with the squad, so that is good news. Hopefully they will be available for Sunday. Diaby is back on the pitches, so that is good news," Wenger told

"At the moment that is all because the other injured players are not back, not Wilshere, not Ozil. Everybody else is alright. He[Koscielny] is still out. The earliest [he will be back] is next week, the latest is the week after. The FA Cup will be too soon for him[Ozil], but he will hopefully be back soon after that," he added.
