Arsenal midfielder Granit Xhaka could miss their game against Burnley on Saturday.
Xhaka suffered bruising to his lower back and leg in Sunday’s 1-0 win at Newcastle and is a doubt for the match at the Emirates Stadium.
Alexandre Lacazette is expected to be available to start after being named on the bench against Newcastle following his ankle scare in pre-season.
Meanwhile, Arsenal are set to bank around £5million from Jeff Reine-Adelaide's move across France from Angers to Lyon.
The midfielder, 21, joined Angers from Arsenal on a four-year deal last summer and is set for another move after just over 12 months.
Standard Sport understands Lyon have struck a deal worth an initial £23m plus £2.3m in add-ons, with Angers also due 15 per cent of any future sale.
Arsenal will bank around £5million of that fee after negotiating a 20 per cent sell-on clause last summer.
