I think whether it's Pep, Conte, Tuchel, Klopp or whoever... they would prioritise the signing of a very good DM and then put a very strong title challenge.
I can't tell if they would win it, cause you never know. But they certainly could win it.
I think Pep is the least likely to make it work, because he needs specific players to work his style. Apart form the DM, the RB and GK will not suit him either and he would change those too. But I think with this team and good DM Conte would be the most likely to win it.
