Jack Wilshere is on course to return to full fitness before the end of the season and thus guaranteeing his involvement in the 2014 FIFA World Cup in Brazil, according to the Daily Mail.

The midfielder is recovering from a hairline fracture which he suffered against Denmark in an international friendly earlier this month.

The 22-year-old was on the wrong end of a tackle from Liverpool defender Daniel Agger and was initially feared to be out of contention for the rest of the season.

Arsenal and England are already without the services of Theo Walcott, who has been ruled out for the season with an anterior ligament cruciate injury.

The midfielder is currently hitting the gym at London Colney and working on his fitness and core strength to maintain himself physically before returning to full fitness.

The Arsenal medical team is watching his progress closely owing to his history with injuries. The England international has missed more than a year of football owing to an ankle injury over the last couple of seasons.

His progress will be a major boost for Arsene Wenger, who has seen his season peter away owing to a barrage of injuries to key players.

The likes of Aaron Ramsey, Wilshere, Laurent Koscielny, Walcott and Mesut Ozil are all out of the squad, something which has been reflected in Arsenal\'s second half results.

Thomas Vermaelen has come into the squad to deputize for Koscielny and Wenger has urged him to make a statement and help Arsenal finish in the top four.

\"We know Thomas has paid a heavy price for having Laurent and Per who worked well together. But he has an opportunity to show how good he is and I\'m sure he will take it,\" he told www.arsenal.com.

Arsenal host Manchester City on Saturday where a loss will make it extremely nervy for Arsenal in the race to finish in the top four.

Everton are currently six points behind the Gunners with a game in hand with Arsenal set to visit Goodison Park next week where the fourth spot is expected to be up for grabs.
