I wonder how many of the Spurs fans in favour of attempting to force Lucas Moura to agree to a transfer before his contract ends by threatening lack of playing time and such were up in arms about Harry Kane wanting to leave Spurs with 3 years on his contract and turning up late to pre-season last year???
I would assume none, because that would be a teensy bit hypocritical.
It is very often a one way street with fans. As soon as they view a player as disposable he's essentially trash to them, see the treatment of someone like Winks who isn't really good enough but still isn't nearly deserving of some of the abuse he receives.
Lucas has given his all for the club & provided a great moment, if he wants to see out his contract and is happy with a bit part role, great.
