Still can't say 100% what type of contract it is though. Spurs are adamant that they will not break their pay structure for academy (FWIW - I think this is the right policy, even if we loose a player), as the tweet makes no mention of money it could quite possibly be a revised academy contract incorporating first team squad number and game time but still on £45k pa. Or it could be a pro-contract for the New Year.It's a pro contract, as he'll be 18 in December. You can't sign a pro-contract until you're 17, which he did not when he turned 17 and seems to have been in a stand off since, waiting on a guarantee that he will get game time, as he could earn 10 times as much and not play for City/Chelsea.
My guess is it's a revised academy contract, same money, with squad number and playing time. Playing time will obviously have strings attached in that he would have to no doubt train well enough to warrant same kind of selection (a lot harder to do this year without EL). We all know he has been offered stupid money by other clubs, but he will know the clubs after him have no track record of playing anyone from their academies.
This deal shows commitment from us, shows we rate him and that we trust his ability. It also rewards him a window for him to prove himself. The timing is perfect in that Kane, Bentaleb and Alli (may be Pritchard, Onomah, Winks) are young players who didn't focus on money but focused on playing and are now getting rewarded for it, so it shows we are not bullshitters. Focus on playing well, getting selected, getting noticed. If he takes his opportunity and shines like Kane and Alli, he knows we will reward him and he will continue to play because we have a manager who encourages it.
Or he flops in training doesn't get selected and fucks off to Citeh or Chelsea to be loaned out to Vitesse never to be see again apart from dropping off his diamond encrusted Doris at the nail bar in his Ferrari.
