Arsenal boss Arsene Wenger has confirmed that Alexis Sanchez will return to the squad during the Gunners' English Premier League clash against Leicester City on Tueday.

Alexis Sánchez, who has been very impressive for Arsenal since his £35 million switch from Barcelona last summer, scoring 18 goals in all competitions so far, has been out of action after picking up a hamstring injury during their 3-2 win over Brighton and Hove Albion in the fourth round of the FA Cup last month.

Although the Gunners did not miss him during their crushing 5-0 win over Aston Villa on 1 February, the Chilean absence was duly noted as a lack of attacking threat resulted in Arsenal's defeat in the North London derby on Saturday.

And now Wenger has confirmed that Sanchez is fit to face the Foxes on Tuesday.

"Sánchez will be back in the group," Wenger told Arsenal's official website. "He is our best goalscorer and one of our hardest working players in the team. It's good to have him back."

Wenger also confirmed that Jack Wilshere has returned to full training, although the Frenchman says that he does not know when the midfielder will be full fit.

"He's back in full training this week. I don't know exactly [how long until he returns], we have to monitor him on a daily basis and see how he develops," he added.

Finally the 65-year-old Frenchman revealed that Alex Oxlade-Chamberlain is still recovering from a groin injury, and will be back after only two weeks.

"Oxlade-Chamberlain is about two weeks," added Wenger.

Meanwhile, Wenger has demanded a much improved display form Arsenal following their 1-2 defeat to the Spurs in the North London derby.

"It is not the first time we lose a game, but how we bounce back is to take the information from what we got at Tottenham, and respond very quickly on Tuesday," Wenger told Sky Sports.

"It is disappointing because we did fight hard together, but we made too many technical mistakes. We lost too many balls in situations where we could have put Tottenham in trouble.

"What is funny is that every time we arrived in their final third we looked like we could score a goal, but we didn't do it enough."
