His Spurs career in stages, IMO:.
1. Awful signing, one of the clumsiest players I've seen.
2. OK to take a place on the bench, but just to bring on for the last ten minutes or so.
3. OK to play against 'smaller' sides in the early rounds of cup competitions.
4. Probably got more playing time than expected, due to our horrific injury list. He tried his best and ran his heart out, but not always effective.
5. Confidence started growing and got a couple of decent performances in, started to make his mark on a game and win some of the supporters over.
6. Transformation into a beast of a player, one of the first names on the team sheet, and someone whose name we sing at the top of our voices. Starting to seem like a bargain
I agree that he and Serge seem to have garnered a reasonably good understanding on the pitch, and it should get better over time.
We love a trier, and no-one tries harder than Moussa. I hope he feels the love.
