Gavi was having good days in Barcelona and he had good performances in the games for this team and considering his age, he couldn't have a shining future in Barcelona. But sadly he got injured hardly while he was playing for Spain during the last November, Just after that there was much news about his situation and he had to stay out for 8 to 10 months to get back in the good form again.
While now we have seen some pictures from Gavi training in the field which can show this player can get back to the field and play for Barcelona again.
Hansi Flick must see Gavi as a good player to have in Barcelona's main line-up next season. Romeo, Ilkay Gundogan and Roberto certainly have more experience than Gavi, but in terms of energy I think Gavi is still quite good compared to them. Gavi can sometimes be decisive, it has developed well under Xavi for several seasons.
