The two areas of the pitch that need some work are up front and midfield.
Hopefully Mo signs a new deal. If he does, I would sell Mane in the summer, as he can still command a decent fee. Origi and Minamino also need to go. Sign a new striker/goal scoring winger. We’ve seen plenty of names. You would have to think there are several good options around the 50M mark.
Salah, Jota, newbie, Firmino, Gordon
Midfield. Milner moves on. Sell Keita and Ox. Just one robust player coming in will make a big difference. Tchoumeni rises to the top of the class for me, around the 40M mark, and if not him, someone of that sort of profile.
Henderson, Fabinho, Thiago, Tchoumeni, Elliot, Jones.
And now one player who can make a difference up front and in midfield. Nkunku.
I don’t know about release clauses and whatnot, but Nkunku and Tchoumeni could be bought for 80-100M.
Selling Mane, Keita, Ox and Minamino will see us go a long way toward bringing that sum in.
Then add in one or two young players like Carvalho at Fulham, who, with a fair wind and further development under Klopp, could become first team squad caliber in time, or if not, sold on after further development with us for a decent sum like Solanke and Brewster.
All of the above is very doable, and also living to our means. Midfield and attack is refreshed, the talent level stays high, and the age profile comes down.
