Delusional. Once upon a time sure, but he's damaged goods in every sense.
Disagree entirely. He's lost his way, but he's still only just 25, has 2 elite seasons under his belt in the past, is mobile, tall, strong and technically decent. He went off the boil under Pochettino towards the end, but Mourinho used him as his scapegoat as he does at every club - see Shaw at Utd - and I think given a new challenge and some direction, there's still an excellent player there.
Last year he only got 15 games and was poor, granted. The season before, 16 G+A in 35 matches, the one before that, 11 in 35, the season before that, 21 in 36 and his best season was the one prior, where he got 29 G+A in 42. It perhaps points to a decline, I think given Spurs' own decline in that time, it's more of a loss of form. He can recover, he just needs the right environment. He's had one truly bad season and he's been written off as 'damaged goods.' Why exactly?
