Inter Milan sporting director Piero Ausilio says it makes him said that former player Philippe Coutinho is shining at Liverpool.
Coutinho left the Italian giants in January 2013 for just £8m and has just been shortlisted for this season's PFA Player of the Year after a number of brilliant performances.
"He was just 18 when he arrived at the club from Vasco," Ausilio told Sky Italia.
“Then came Benitez and the expectations were very high. Rafa used him on the flanks in a 4-2-3-1 formation.
“He was not playing much and we lacked patience so we decided to sell him.
“I would like young players to grow and succeed here; when I seen them play for other clubs, it makes me sad.”
