It sounds like we want two marquee, world class players at ST and CM and then we also want 1-3 younger players that we can develop. I assume most of this, if not all, will be done in the summer unless someone unexpectedly becomes available this month. A signing like Cunha or Kubo strikes me as more of an opportunistic signing to fill a gap as we try for the title and independent of that. The names mentioned for the marquee signings have been Isak (of course) and Reijnders from Milan, who I absolutely love to watch. The other names I saw for the younger signings were Jobe Bellingham, Adam Wharton and Tyler Dibling. I'd love any of these players personally and a summer with the two headliners and 2 of those 3 would be a spectacular summer IMO.
I really like Cunha but my only worry would be his fit in the team, as he's not an out and out winger or striker. It feels like we have two players of a very similar profile in Jesus and Trossard and while I think he would be an improvement over them (unless Jesus can sustain this recent form), I'd worry about if he could slot in on the wing or add more goals through the middle - which is what I think we should be focusing on if we are to sign anyone this month. Kubo is much more of a natural winger but his output leaves a lot to be desired (10g/4a over the last two seasons, although he had 9g/4a in 22-23). If we are going to be spending 60m+ on a January signing, I'd rather dangle that in front of Bournemouth for Semenyo and see if they blink, as I think he'd be perfect for us now and as we develop in the next 2-3 years as a great squad player/starter.
