During Roma's training session on Wednesday, an unexpected guest visited - retired famous striker Christian Vieri.

However, Vieri will not return to the team he represented in 1998-1999 - he was invited to participate in training for a few days, as some players are away representing their national teams.

"It's a good opportunity to sweat a bit, maybe I will even lose some weight," joked Vieri. "Don't worry, I have no intention of restarting my career."

When asked if he misses football, the Italian answered: "To be honest, not really. I thought it would be harder, but sooner or later the time comes for that."
