They have already shored up the biggest weakness they had by replacing Upemacano for Boateng.
This year they would have beaten PSG easily if Lewy hadn't been sidelined for those 2 games. MC would have been a test, but the 2 teams would have given the best game of the tournament in the Semis. If they got past MC, they would've destroyed Chelsea, imo. They look to be better next year.
