Chile striker Alexis Sanchez will be back in the Arsenal squad for Tuesday’s Premier League game against bottom club Leicester City as Arsene Wenger’s team look to bounce back immediately from their derby defeat by Tottenham Hotspur. Sanchez, who has scored 18 goals in all competitions this season, missed the 2-1 loss at White Hart Lane on Saturday and the previous week’s 5-0 win over Aston Villa due to a hamstring injury.

“Sanchez will be back,” Wenger told reporters on Monday. “He is our best goalscorer and one of our hardest working players in the team. It’s good to have him back.”

Alex Oxlade-Chamberlain, however, will be out for another two weeks and Wenger had no date for the return of Jack Wilshere.

Leicester, who have not won at Arsenal since 1973, have lost on their last seven league visits to the red half of north London, and will be looking for the kind of upset they inflicted on Spurs when they visited them two weeks ago.

Leicester beat Spurs 2-1 in the FA Cup will need that kind of resilience against an Arsenal side who had won five successive matches in all competitions before the loss at Tottenham.

Leicester will have manager Nigel Pearson in charge after the Foxes issued a statement that reports he had been sacked were “inaccurate and without foundation”. Pearson became involved in a touchline squabble with Crystal Palace midfielder James McArthur during Saturday’s 1-0 home defeat after the player accidentally crashed into the Leicester manager.
