Apart from the obvious issue of not signing a single outfield until January, let alone a much needed striker these are to me the fixtures that caused our season to unravel.
I've whittled it down to eight fixtures
Chelsea (away) - 19th September 2015
Chelsea had made a truly awful start to the season and we had recovered after our own poor start. But again we showed our psychological frailty when playing a Mourinho managed side. A poor refereeing performance didn't help but let's face facts up until the time of Mourinhos sacking he managed to win twice more in the league against Aston Villa and Norwich.
Diego Costa should have been sent off but Gabriel should not have reacted
West Brom (away) - 21st November 2015
What makes a title winning side is to play badly and win, here we played well but contrived to lose with Cazorla even shooting over the bar when we were awarded a penalty to level things up. Gift wrapped both goals to the Baggies and missed a succession of presentable chances in the second half.
Southampton (away) - 26th December 2015
Defeats happen even in an otherwise good season, but from kick off to final whistle we just didn't look like a side that could be bothered, everything we could do wrong we managed to get wrong. Pushing up too much and allowing Southampton to get in behind us, constantly losing posession and creating nothing in the way of goal scoring chances
Chelsea (home) - 24th January 2016
Again an example of Chelsea being able to beat us with the minimum of effort, they know how to play us and failing to score in almost ten hours against Chelsea in the league is truly apalling, especially a Chelsea side that looks unmotivated and directionless.
Southampton (home) - 2nd February 2016
Fraser Forster made a lot of saves but none that he would not have been expected to make, the point where both Leicester and Spurs overtook us in the table....we have not been higher than third since.
Manchester United (away) - 28th February 2016
Pundits believed that due to a catalogue of injuries for United plus their own indifferent form meant this was a likely win for us, it appeared that the players believed it as well and put none of the effort in required to secure that win. Defeats happen but they happen to Arsenal more often than not because the side can't be bothered to apply themselves.
Swansea (home) - 2nd March 2016
Typical Arsenal any poor performance has a knock on effect, totally inept performance and the point where we realised that the title had predictably evaded our grasp.
West Ham (away) - 9th April 2016
Anything can happen in this league even if you are eight points behind, but we failed to put any pressure on either the league leaders or the team in second by completely collapsing after getting a two goal lead. Even not winning the title could have been mitigated by fighting to the end of the season but fight is what we lack.
