I agree Conte's good track record when he coached several big clubs is a guarantee that Conte is the right coach for Tottenham.
Actually, it is not a guarantee that Conte will be fit with Tottenham players. However, with a good track record, we can expect that Conte will have a big chance to improve the players' performance with his capacity.
I want to see Tottenham's performance for the next 5 games, we can judge Conte's quality as a coach.
I don't think the result of the next 5 games is enough to determine the Conte quality as a coach. It is too early, he may lose in some matches because he still needs time for adaptation. At least, we must wait for till half of the season is over. Then, we can see how good the progress of players' improvement during managed by Conte.
Players to be sold include Dele Alli, Steven Bergwijn, Lucas Moura and Giovani Lo Celso.
Alli is a good midfielder, I think he doesn't need to be put on the transfer list. This player has an important role and seems can play better if he is managed by a good coach.
Conte plans to bring in 6 players from Serie A. Such as Chiesa, De Light, De Vrij, Brozovic, Romagmoli and Vlahovic.
Good choices, but I am not sure it will be easy to sign them. Especially De Light, De Vrij, and Romagnoli, these players can be targeted by other top clubs. Tottenham must make an interesting offer for them if really want to have them on the squad. Probably will compete with some top clubs to sign them.
