Liked Chiesa years ago at Fiorentina but after all injuries would just be too risky. Also knowing history of Italians at Barca, they just don't do well here. If we'll sign him there are big chances we'll be looking to offload in 10-11 months and only offers we'll get will be loans from Serie A teams with Barca covering at least half of his wages.
NEVER buy players who have a good pedigree in Serie A with hope you can sell them back there if things go wrong. Juve, Inter, Milan&co. are cheap ass clubs. We should know this by now with our previous experiences dealing with them.
IF you can get a player with a good history from PL then at least you can hope to sell him to another PL club if he doesn't make it here though we're even letting these players go for free now, lol. But same won't happen with Italian players and clubs.
Is it really worth to invest 20m+ (let's say 13m fee and 9m wages but will probably be more) for Chiesa in a season when we won't win anything. I just don't see him being a difference maker between winning nothing and something (and tbf I don't see any player we can realistically sign to be that kind of difference maker so that's not a knock on Chiesa) this season and not being a long term answer at LW either. Would prefer to just keep Ansu. He would count around the same against salary cap but is already registered so don't need to worry about that. And they both have injury history and are likely to miss games.
Here they are compared in last two seasons.
Chiesa (Serie A): 54 games, 11 goals, 8 assists, 3.050 minutes (goal contribution every 160 minutes)
Ansu (La Liga+EPL): 55 games, 9 goals, 4 assists,1.893 minutes (goal contribution every 145 minutes)
Keep in mind that Fati was basically a healthy scratch for most of second half of last season and I'm sure he would provide more goals if he'd play as he was actually playing well when given a chance.
