Barcelona coach Ronald Koeman regrets not having the chance to work with Carles Perez.
The Barca winger left for Roma on-loan in January before eventually signing permanently.
Corriere dello Sport says Koeman is a fan of Perez and is sorry he didn't get the chance to work with the midfielder upon his arrival.
The Dutchman isn't the only one, with several directors sharing the same opinion.
Perez has begun the new season with Roma impressively and is already off the mark.
