Real sociedad played 42 games last season sandro started 11 games and was a substitute in 15 he played a grand total of 1241 minutes. The equivalent of 13 full games out of 42. His starts he played as a striker 6 times out of 11, 4 more then any other position.
His best stat for sociedad was his shots on target 1.8pg his second highest stat was his bad touches 1.5pg his third was being fouled 1pg. All his other stats are under 0.9pg his pass% is alright (78.1%)untill you see how man passes he makes a game (14.1).
In all of the 27 games he played last season do you know how many times he was directly involved in a goal? Once and it was a assist for everton in the leauge cup against Rotherham.
So, yes. I think we are all well within our right to say he had a very poor season and is crap.
