Auba can't get a game for Chelsea & was poor for 1 or 2 seasons before he joined us he had a nice purple patch due to new surroundings, that's about it.
He wouldn't have been up for that long slug of a season, too busy flexing for the gram.
Don't know if it's form or just the inevitable decline has arrived.
Still, on a free I'd take him back.
If a perfect world I work have kept him, at least have someone to rotate with lewa & play off the left if needed, but it was too good of a deal.
