4 reasons why Arsenal won against West Ham

#3 Crucial saves by Petr Cech

The fact that Petr Cech is still in the starting eleven tends to surprise the fans, as their new signing Bernd Leno hasn't got a chance to show his set of skills, yet. People claim that Cech is light years past his best, and he no more delivers to the team.

But the fact that he is still the most clinical player in the squad is often hidden under his few unconvincing performances. Cech's saves turns out to be pretty crucial for the team, and the 36-year-old still has a lot to give.

Arsenal's defence has been least desirable and their inability to keep clean sheets is what Cech is criticised for. Emery is trying to make changes in the squad and as a result, he has signed 4 players, out of which two are defenders.

He certainly aims to ameliorate the defence, but his first two games have ended in a defeat, primarily because of a weak back-four.
