He *built a quality team. Don't forget Son was not what he was when they bought him, there was very little hype there, just a solid player from the Bundesliga. Sissoko was seen as laughing stock and people were amazed that Spurs paid £30m for him. Dele Alli came in from MK Dons. Lucas Moura was not a starter at PSG. Trippier was second in the pecking order to Walker. Alderweirald came in from Southampton. Kane had just come through with his good form in the Europa League the previous season. Wanyama, while linked with some of the bigger clubs, was still as an uncertain young player.
When looking at this Spurs team I see a masterfully crafted set of players. If I had the budget that Poch has had I don't even think I'd be able to replicate this on Football Manager (admittedly I'm not that good, but still, it's saying a lot cause it's so easy on that game to craft a good squad).
