Arsenal assistant manager Steve Bould has admitted that he is "unsure" whether Alexandre Lacazette will be fit to face Stoke City in the Premier League on Sunday afternoon.

Lacazette, who underwent a knee operation last month, returned to first-team training with the Gunners over the international break.

The 26-year-old has been tipped to return to the Arsenal squad for this weekend's clash with the Potters, although Bould has admitted that a decision over the striker's involvement is yet to be made.

"I don't know. He's trained, he trained yesterday but whether he will be involved at the weekend I'm unsure," Bould told reporters.

Lacazette, who moved to the Emirates Stadium from Lyon in last summer's transfer window, has scored nine times in 29 appearances for Arsenal during the 2017-18 campaign.
