Milan still looking for the players this summer but indeed so far it just a rumour and there was no certain news about who is the player that will be bought by Milan and apparently Pioli currently want to focus looking for new striker because after Ibrahimovic got retired and Brahim Díaz return to Real Madrid then automatically Milan only have Olivier Giroud and they cannot rely on this player for whole season especially Giroud have already 36 years old so Milan is required to buy new striker and indeed they have Divock Origi but after transfered from Liverpool Origi seems has lost his touch and cannot able to performing well
I was found one name who possibly will bought by Milan and it was Borussia Monchengladbach player Marcus Thuram and after decide will not to extended his contract in Monchengladbach reported some of big clubs were interested to Thuram including Milan and the latest is PSG and Pioli feel Thuram can be suitable as the replacement of Ibrahimovic that's why he personally will try to persuade Thuram to moved to Milan and if Thuram is willing to move to Milan then they will offering long term contract duration to him
I agree that Milan's main target should be to buy a much more reliable striker from now on. Giroud and Origi can't show the expected the level of performance. Giroud makes some contribution with goals but the number of them isn't so many. Origi was transferred with nice hopes but he was much worse than Giroud. I don't remember Origi scoring more than a couple of goals.
If Milan increase the productivity of their attacking line then they can be much more competitive for the Serie A title again. I know Leao is doing great also by scoring so many goals despite not being a striker. But this isn't enough. Milan would make use of a striker who can be even in top scorer rivalry.
