Robert Pires believes Arsenal can challenge for the title next season if they keep Alexis Sanchez and Mesut Ozil and sign Kylian Mbappe or Alexandre Lacazette.

Boss Arsene Wenger wants to sign both strikers this summer, but Pires believes it is also crucial Sanchez and Ozil stay at the club.

The former Gunners forward said: "The most important thing is to keep Sanchez and Ozil and if they buy Lacazette and Mbappe.

"Arsenal can do both - they can extend the contracts of Sanchez and Ozil and why not buy two or three players?

"If Arsene buys some players they can lift the Premier League trophy."

Speaking at the launch of the new Arsenal Puma kit, Pires added: "Mbappe is a great player who has good potential.

"Of course he is very expensive but now in the UK anything is possible.

"Lacazette is a great player. And I love Ousmane Dembele at Dortmund, too."
