Don't get me wrong, I'm not saying he was good either. Certainly wasn't at a level where he should have been a starter. But I think he was a decent level for a backup player, so saying he was terrible is harsh. While he wasn't adding much to the attack, it was noticeable that the team as a whole played better when he was in there. I remember looking into it at one point and (pre-Bruno joining) it was ridiculous how much better our results were with Pereira in a more attacking role than with Lingard or Mata. From memory, when he played at #10 our points per game was something like 2.2, when he played right wing they were 1.9, and when he either played in central midfield or didn't play at all it was just 1.2.
Obviously it was fairly small sample sizes, and it's also showed how bad both Lingard and Mata were that season (they were both so bad I'm not sure if 'terrible' does justice to it), but Andreas was easily our best option in that position before we signed Bruno. Ole dropping him down the pecking order behind both Lingard and Mata despite him easily outperforming them is one of the stranger decisions he made here.
