Conclusion
Seri has a £35 million release clause according to reports, which is a good price based on current transfer market inflation. He has room to grow as well as youth on his side, so he would be an excellent investment. He would be the closest replacement to Verratti, but the major issue with him is his lack of experience.
Fabinho is likely to cost at least £40 million because Monaco rejected a PSG bid of that amount. They are more likely to sell to Barça than a domestic rival, but he still won’t come cheap. There is also competition from Premier League clubs such as Manchester United who could offer better wages. He would have to adapt to Barcelona’s unique style which may take time. However, he proved that he is equally capable on the big stage with the two legs against Manchester City being great examples.
Jorginho doesn’t have a release clause and Napoli rejected a £15 million bid from Arsenal, although, his agent denied it. Therefore, it is unclear how much it would take to pry him away. Anything more than £30 million is likely to be too much based on his limited talent ceiling. The similarity in playing styles between Napoli and Barcelona means that it is likely he would have an instant impact.
Each of the players would bring something slightly different. However, each of them would be a good, cheap alternative for Verratti. Some would argue that the decision to buy André Gomes over Paul Pogba suggests that going for the cheap alternative isn’t a good idea. However, Verratti looks extremely unlikely to move and these three all have the capability to be excellent alternatives. The team needs a player capable of bringing control to the midfield, regardless.
