Chelsea are reportedly 'growing increasingly confident' of signing Alex Oxlade-Chamberlain before the end of the month.
The 23-year-old scored twice and registered seven assists in 29 Premier League appearances for Arsenal during the 2016-17 campaign, but he struggled to hold down a regular position in the team.
The England international has started the new season as a wing-back in Arsene Wenger's new formation, but he will be out of contract with the Gunners next summer.
According to The Telegraph, Arsenal have offered Oxlade-Chamberlain the chance to sign a new £180,000-a-week contract at the Emirates Stadium, but Chelsea are confident that the versatile midfielder will reject the offer to move to Stamford Bridge.
Oxlade-Chamberlain has scored 20 times in 196 appearances for Arsenal following a 2011 move from Southampton.
Alexis Sanchez, Jack Wilshere and Mesut Ozil will also see their current contracts with the Gunners expire next summer.
