You want to know Wengers excuse (assuming Leicester win the title)? "We beat Leicester home and away last season, so we are not far away. Injuries did not help us as Cazorla, Rosicky and Welbeck were not available for almost the entire campaign. If we have fully fit squad to chose from in the new season, we will make top top effort."
He may also add our statistic of going the last 8-9 games unbeaten towards the end of this season. I know there are still games left but with the pressure off, I can see us going on a run. If inevitably we do, add some shit about that to the above part as well.
Rinse. Repeat.
