With regards to Barça, I'm hoping the club is conservative with their money unless of course they can make something from Coutinho or potentially Griezmann. Of course with the chaotic board situation I could see Bartomeu printing money to make a big signing.
I'd be very open to a swap deal too, but most certainly not Semedo for Cancelo. Swapping Rakitic would be nice, but I think he only wants to go to Sevilla to be closer to his wife's family.
The good news is that we plenty of players the club could use to bolster the first team without spending much if any money. Puig could be promoted. I'd even consider Monchu and both Araujo and Collado have been considered. Trincao is on his way. Todibo back from loan would be fantastic. Emerson could be bought for cheap. Alena and Busquets could come back from loan. Even Coutinho, who is surely out the door at this exact time, is someone who could be brought back.
