I didn't say they can't play in the same position. They can play in the position - i.e. a fluid AM role - but Lo Celso doesn't also play as a forward, unlike Dybala.
For Spurs, and the way we play and are set-up, Lo Celso is probably a better fit. If that opinion puts your nose out of joint for some reason, then too bad.
Spurs are rubbish
