Honestly watching Auba, especially at the start of the season, he looked like he was putting huge effort in. The fact he was actually going in physically with defenders for long balls and actually winning them showed me that.
He was just hardly getting much service and when you get one half chance a game it plays with your confidence. He looked like he was struggling with confidence and form and coupled with the lack of service it just wasn't working.
Never got the impressuon he wasn't trying though, at least not this season.
