That looks a little too thin and unbalanced in the midfield for me. Spurs' easy fixtures are over, so I would downgrade Son (who only scores against teams who leaves space for him) to avoid having a "dead" 5th midfielder. There plenty to choose from between 5,5-7,5M. In other words: I'd much rather have two of: Martinelli, Bowen, Gordon, Mitoma than Son + a 4,3. Easy!
And I think it's a bit risky to go with Taylor + two stand ins (Lascelles and Tsimikas) in the back. Lascelles is probably out of the team in gameweek 12 and Tsimikas is not nailed. Taylor will just, like my Al-Dakhil, give you 1, 0 or -2 pointers for the rest of the season if you must play them.
Trippier, Salah, Saka and that trio up top looks nuts though
