Arsenal could welcome back Alexis Sanchez to their squad for their trip to Liverpool this weekend.

The Chile international was pictured in training alongside record signing Alexandre Lacazette yesterday, with the pair bonding.

Lacazette has scored once in his opening two games for the Gunners and Arsenal fans are hoping to see him link up with Sanchez.

Sanchez has missed the first two matches of the Premier League campaign with injury, but has now returned to full training.

Arsenal boss Arsene Wenger was asked about Sanchez yesterday at his press conference, with speculation still swirling over his future.

Sanchez has not yet signed a new contract and his current deal expires in June.

Wenger told Arsenal.com: "He is very focused, very happy and as I told you before, the fact that he goes into the last year of his contract does not mean we have no chance to extend it.

"At the moment we have not managed to do it, but we just want to focus as a team and not look too much at the individual conditions of the contracts of everybody because what is important is what you want to achieve forever."

Sanchez is expected to be under consideration for selection this weekend, and Wenger gave a hint towards that by also confirming the attacker is available to travel with Chile for their World Cup qualifiers next week.

Liverpool pipped Arsenal to a Champions League qualifying place last season, and currently have a one point advantage over the Gunners in the Premier League.

Arsenal will be determined to prevent that extending to four points this weekend, and Sanchez could end up playing a key role.
