PREVIEW By Arsenal correspondent Tony Hughes

Out of the Champions League. Out of the FA Cup. The success of Arsenal’s season now rests upon clawing back an 11-point gap on Premier League leaders Leicester.

Saturday’s trip to Everton is now of the must-win variety if Arsene Wenger’s team are to rescue something from a desperate week.

The key team selections are likely to be in the attacking positions as the manager tries for a combination that will provide greater goal threat than Arsenal have managed in the last few weeks.

Alex Iwobi delivered an encourgaing display after surprisingly getting the nod ahead of Olivier Giroud, Theo Walcott and Joel Campbell against Barcelona in midweek.

Leading scorer Giroud, whose tally of 20 goals in all competitions is nine more than closest challenger Alexis Sanchez, is likely to return to spearhead the attack.

This could mean the impressive Welbeck being pushed out to wide position, if the coaching staff are confident he can start his second match in four days during what has been an intense re-introduction to the team following his 10-month absence with a knee injury.

If Welbeck is in the starting X1, the final place could be between Walcott, Campbell, Iwobi and Alexis Sanchez, whose mediocre form continued at former club Barca on Wednesday.

Arsenal (possible): Ospina; Bellerin, Gabriel, Koscielny, Monreal; Elneny, Coquelin; Walcott, Ozil, Welbeck; Giroud.
