Ofcourse we don't know but it doesn't justify the decision to take him off! And I doubt anyone was saying Mourinho should take risks away at Arsenal but the substitutes did not have any impact. Hazard and Willian both off meant that the attack was disjointed for the last few minutes. Don't mean that he should have thrown on a striker and gone gung-ho for it. A point at Arsenal is good obviously and the performance was also fine but I didn't agree with Jose's subs in the game.
