Arsene Wenger has made three changes to the Arsenal team for Sunday’s FA Cup quarter-final against Watford.

The competition now represents the Gunners’ best chance of winning some silverware this season and Wenger has responded by selecting a stronger side than the one that brushed aside Championship club Hull 4-0 on Tuesday night.

Mesut Ozil, Alexis Sanchez and Francis Coquelin replace Alex Iwobi, Theo Walcott and Mathieu Flamini in the line-up.

Danny Welbeck and Hector Bellerin were also given breathers in midweek but they are named on the substitute’s bench, while there is no place in the matchday 18 for Laurent Koscielny even though he trained on Saturday.

The Watford match at Emirates Stadium is the first of three pivotal matches in seven days, with Wednesday’s Champions League trip to Barcelona followed by a trip to Everton in the Premier League title race next Saturday.

Wenger knows he cannot throw away the chance to win a competition that will require just three more victories to clinch a record third consecutive FA Cup triumph.

Olivier Giroud spearheads the attack and is likely to need to produce another convincing display following his two-goal performance against Hull to nail down a starting place against Barcelona.
