I'd add Gerrard in his prime to that list. In fact Alli reminds me a lot of Gerrard but with a far higher ceiling. We need to (& should) be seriously challenging top 4 to keep this young & highly exciting group of players together.
I'm obviously biased but I can't think of a squad in the league I would rather have than ours. Maybe take the odd player from another team but as a whole I think it's quite remarkable what has been assembled for the cost. Some of the big spenders must be gnashing their teeth & salivating at what we have. Keep the core of the team together & I think the sky's the limit.
Exciting time to be a Spurs fan.
