The north London side head into the game on the back of their 2-0 win over Bournemouth last weekend, with Oxlade-Chamberlain netting his side’s second goal after Mesut Ozil’s opener.
Arsenal have struggled to find consistent form since the turn of the year and went four games without a win in the Premier League before last weekend’s victory.
However, Oxlade-Chamberlain has called for focus from his team-mates as they prepare to welcome the high-flying Foxes to Emirates Stadium.
The England international shared the picture above on his personal Instagram account and wrote: “Training done. Focused on tomorrow’s game #COYG”
Arsenal, who finished third and won the FA Cup last season, have not lifted the top-flight trophy since their famous unbeaten triumph in the 2003-04 season.
The Gunners are currently third in the table and five points behind Sunday’s visitors to Emirates Stadium.
