Arsenal boss Mikel Arteta wants his side to play with "pure fire" as they prepare for one of their biggest weeks in years.
The Gunners host Sporting on Wednesday, having won 1-0 in Lisbon last week, for a place in a Champions League semi-final.
That was the only victory for the Premier League leaders in their past four games, having lost in all three domestic competitions.
On Sunday they visit Manchester City, their closest challengers in the title race.
Having last won a trophy in 2020 with the FA Cup during Arteta's first season in charge and not been league champions for 22 years, the pressure has intensified on Arsenal to deliver success the club and fans have craved.
