Arsene Wenger must extend Alexis Sanchez and Mesut Ozil deals before making signings, says Robert Pires

Arsenal legend Robert Pires believes the upcoming summer transfer window will be crucial for the club's ambitions of winning the Premier League title next season.

Arsene Wenger's side have already agreed a deal to sign defender Sead Kolasinac on a free transfer, and are now turning their attentions to recruiting a striker - with Monaco star Kylian Mbappe and Lyon's Alexandre Lacazette on the club's list of targets.

Pires has already called on Wenger to do everything he can to keep Alexis Sanchez and Mesut Ozil at the club while trying to reinforce his striking options.

And the Frenchman, who won two Premier League titles and three FA Cups during his time at Arsenal, believes the Gunners' activity in this summer's transfer window could play a big role in how well the club does next term.

"This summer for Arsene Wenger is very important," Pires told Arsenal Player. "In my opinion, he needs to try to extend the contracts of Alexis and Mesut Ozil. This is the first thing, and after of course you need to sign new players.

"Everything has changed because we’re not playing in the Champions League, but we must focus and look forward to the new season. The most important thing is to win the Premier League, for him, the players and the fans.

"I believe in Arsene Wenger, I believe in this squad, I believe in the young players like Alex Iwobi and Hector Bellerin. When I see the name on the paper or the squad, it’s very good.

"Some players can play at a very high level and play for the national team. Maybe Arsene Wenger [would like] two or three more players but the stability is here because he’s extended his contract."
