AS Roma chief Monchi has defended their recent transfer policy.
The likes of Mohamed Salah, Alisson Becker and Antonio Rudiger have been lost over the past year.
Monchi told Planet Futbol: “We are working above all to find a sustainable economic model, which would allow us to decide who to sell and when. We are on the right track, but that doesn't mean we won't sell in future, because selling players is not a bad thing.
"It's normal and then you reinvest that money in structures, Coaches and players who can help the club grow.
“In football, everyone sells players. Barcelona sold Neymar to PSG, Real Madrid sold Cristiano Ronaldo, while Juventus sold Paul Pogba and Gonzalo Higuain. Clubs must be smart when reinvesting the money."
