[Getty Images]This was a tricky assignment for Arsenal after suffering back-to-back defeats in the league for the first time this season and losing to Manchester City last week.However, the Gunners navigated through this difficult match to secure a vital three points in the title race.The short corner with which they took the lead - their 17th goal from a corner this season - was initially not welcomed by supporters with Martin Odegaard gesturing for calm from his own fans as the Gunners celebrated what proved to be their winner.When Kai Havertz was withdrawn through injury in the first half and Viktor Gyokeres was subbed on in his place, the Gunners lost their ability to hold on to the ball upfront.That will be a worry for Arteta at this time of the season and with the Champions League semi-final against Atletico Madrid coming up next week.Eberechi Eze had to be withdrawn too but all that will matter to Arsenal fans is that they managed to secure what could be a crucial three points in this title race with Manchester City.The Arsenal players fell to the floor with the effort they put in and now they have given themselves the chance to double their lead at the top of the table next week when they take on Fulham before City are next in league action.
