If Chelsea haven't pulled the trigger on Nkunku we should give it our best fucking shot - same kind off deal - sign and let him stay until the end of the season if necessary. I believe he's got a summer release clause that's about 60m Eur.
Upgrade on both Son and potentially Kane - and there aren't too many of them available. Boy can play different positions, technically excellent, quick, strong, lively as fuck and scores all sorts of goals - and creates them.
Failing that, go for Leao. Similar vibe, can do more than just score, can run at players and create for others, can play wide left inverted forward but also down the centre. Not quite as good as all-round wholesome Nkunku but would be an upgrade on Son in terms of all round game, and would eventually give us a Kane replacement.
We also desperately need some more quality creativity, whether that's advanced players or 8 types.
