Sampdoria chief Walter Sabatini says AS Roma midfielder Javier Pastore has failed to reach his potential.

Sabatini first signed Pastore for Palermo.

“I did suffer when having to sell certain Roma players, but it was a problem the club simply had to face up to and deal with," said Sabatini.

“There are many players who disappointed me over the years. An example is Pastore, who at Palermo played the kind of football that you can only imagine in your dreams. Then he went to PSG and rested on his laurels, just put his feet up and coasted.

“It's so sad, because he could've achieved so much."
