I would argue that we need two centre forwards. Dream scenario would be to bring in Moukoko now for say £10m (contract ends in the summer), and he can cover/ rotate with Martial for six months, and then we go for Kane in the Summer.
Each of the three offer quite different things, and because of their situations, all could do with managing their playing time. Kane will be over 30, so not able to play Saturday, Wednesday, Saturday every week, Martial is often injured, and arguably not the required level of quality, and Moukoko is still raw, and you wouldn't want him having the pressure of being first choice striker at United as a teenager. Kane guarantees goals for a few years, and gives us time to properly assess the number 9 market, both Martial and Moukoko from within, Osimhen and Sesko (at Napoli and RB), and anyone else who steps up. Or we just go for the outstanding candidate - Kylian Mbappe, finances permitting.
CM the obvious candidate is FDJ.
CB we need someone capable of slotting straight into the first team, and good enough to replace Varane. I wouldn't be averse to Kim Min Jae, but not sure how quick he is if we are playing a high line.
RB looks like ETH is comfortable using AWB, or letting him go if we can find a buyer and bring someone else in, so not fussed on this one.
GK looks like it may be sorted this week, with DDG taking a wage cut and Butland as cover.
The final luxury player I would bring in would be Musiala, from Bayern Munich, who looks future Ballon d'or material, to rotate with Bruno for the number 10 role, with Bruno potentially sharing right wing duties with Antony. I think Musiala and Moukoko could build a great partnership as the future of German football, and getting Moukoko in now may help persuade Musiala to join him down the line.
