They have a strong team but in the final game they didn't try a lot to win the title.
It is true. Arsenal is not a weak team, it has a chance to win the game. But in my view, Emery chose the wrong strategy to face Chelsea attackers. 4 goals are enough to show that Arsenal has a problem in the defense line. At that time, Chelsea can exploit the weakness very well. Yeah, Arsenal should take some learning from this case, no place for weakness to win the game.
