The Gunners , who currently sit 4th in the table are four behind Manchester United and a further 12 behind league leaders Manchester City.
The Gunners are in a good vein of form at home, winning all of their last 12 league games in front of the Emirates crowd.
Wednesday’s 5-0 win over Huddersfield Town continued that winning feeling, but Mourinho’s men present much tougher opposition.
‘Sanchez had a little hamstring problem – that’s why I took him off but I think he will be alright,’ said a hopeful Arsene Wenger after the 5-0 victory which strengthened Arsenal’s grip on the top four.
The injuries could see Wednesday’s second half substitutes Danny Welbeck and Olivier Giroud return to the starting line-up.
Giroud is yet to start in the league this season, but did score two second-half goals to take his Premier League tally to 72 – he’s now 4th outright in the leading French scorers.
Gooners, who should be played as the front three if both Lacazette and Sanchez are out? Let us know in the comments…
