He was incredible for us, but, let's be honest, he was no Bale (just like even in 2016/17, Eriksen was no Kane), and as you said, he was dissapointed after 2011 (although I don't remember him downing tools as much as Eriksen).Modric was a brilliant midfielder for us and certainly also in his last season, even though he was disappointed that he hadn't made a transfer in the summer (of 2011).
