Inconsistency ruined his time here. Probably had the best start you could ask for by scoring a brace on his debut in the CL. Just seemed like a one off in all fairness. I guess the crazy amount of games he played when he first joined (75+ in year and a bit) might have contributed to him being fatigued for part of his time, but he just never looked like regaining any sort of form to nail down a first team place once again. The fact he's off to China says more about his lack of ambition tbh. At least he'll be covered for life.
