Well that's the general gist of recent articles and of both Sherwood and Pochettino's opinion of the squad.
Far too many players who might have a high level of basic ability, but no drive, intelligence or determination to apply it and stretch themselves, or to fight and win in a very competitive environment.
It beggars belief for example, that Paulinho hasn't been kicking up a fuss, as he's lost his place in the Brazil team and is in danger of having a second failed stint in Europe on his CV that could kill his top-level career prospects. He doesn't seem bothered.
Capoue similarly has gone from promising midfielder on the fringes of the French squad, to journeyman reserve. Not a peep.
Adebayor has stated he is happy at Spurs and has no intention of leaving??? What???
Just seems there are a tonne of players that aren't even bothered if they're not playing, as long as they're collecting their wages every week, they're happy to sit on the bench or play U21 matches.
That's ultimately why guys like Bentaleb, Mason, Kane and Townsend have been preferred. They're hungry and determined to prove themselves.
