I do think we'll start seeing deals come thru now that the tournaments are over. No big name players moved because even if a deal was agreed, no buyer was going to send wires until they can at least see that the target didn't come off the field on a stretcher.
Not that he was on the move, but Pedri is the only notable player I can think of at Eurocup that came off injured. Not good for Barca with Gavi still rehabbing.
At the Copa, Messi is the one that stands out. But that looked to me like a 1-2 month ankle injury--not torn ligaments. But who knows.
Spurs should be one of the busiest clubs in the world in the transfer market over the next month. They need to move some pretty big name players, namely Hojbjerg, GLC, Emerson Royal (should be heading to AC Milan any day), Bryan Gil, and also possibly perhaps Bentancur, Reguilon, Manor Solomon (still such a weird transfer), Ollie Skipp (probably kept for homegrown purposes though), Djed Spence, and Veliz (loan likely).
There's talk in the Spurs sphere that the club still want to bring in a big name forward, with someone like Eze or Toney being the level in mind. I think both would count as homegrown as well. Conor Gallagher rumors persist, but I doubt it. Another CB would be welcome, but it's not too dire with Romero, VDV, and Dragusin in the fold. A backup keeper is also fairly high on the list.
Barca OTOH, are likely still hamstrung for money. It also wouldn't surprise me if the club stand pat mostly to let Flick see what he has first before reshaping the squad starting in the January window. But nothing surprises me with Barca anymore. If they were run like a business, they'd consider selling any player over the age of 26 with value and investing heavily in the academy to balance the books. But what that means in reality is that they will splash big money for Leao or something.
