As I've said before, This is where Man. Utd - and some Man. fans - get it so wrong. Because of your wealth you've fallen into the money trap .... here's some examples
* You pay astronomical wages to Rooney, although he now contributes relatively little to the team and can't now be moved on because of those wages.
* You commit to paying anything up to close to £60m for a talented teenager (Martial), but ignore the likes of Dele Alli for £5m
* You spend much of your transfer windows chasing 'galactico' or big-name signings, mostly don't succeed, but when you do it's for an over-the-hill player (e.g. Schweinsteiger) looking for one last big pay-day.
* You neglect your scouting, player recruitment and youth development systems ... because the main focus is on buying your way to success.
Spurs will never pay Kane £250-300k per week (nor any other player for that matter). I expect he'll be offered (and will sign) an improved contract this summer for around £100k. I also think he'll be very happy with that, with continuing to play for Spurs and with the prospect of playing in the CL next season.
If he eventually leaves to go abroad for the likes of RM and bigger wages (which won't be anytime soon), then so be it. Spurs would then get a bucket load of money, invest some of it in further improving our youth development system and see the next batch of quality players rise up through the ranks.
