Arsene Wenger says failing to secure Alex Oxlade-Chamberlain’s future at Arsenal would do “big damage” to the club.
Oxlade-Chamberlain, who signed from Southampton in 2011, recently returned from a hamstring injury but has not started a match for almost a month.
However, Gunners boss Wenger insists he wants Chamberlain to extend his contract at the Emirates.
“I personally think it is vital that Chamberlain stays at Arsenal,” he said.
“We bought him when he was very young, we have built him up and I think he has a great mentality.
“I like his mentality and he has a good football brain. It would be a big damage for us to lose this kind of player.”
The England international is one of a number of Arsenal players whose contracts expire next year and who has yet to agree an extension.
Jack Wilshere, Mesut Ozil, Alexis Sanchez and Kieran Gibbs also have 14 months remaining on their current deals.
