Inter signed Coutinho as a teenager from Brazilian club Vasco de Gama, but he failed to establish himself at the San Siro despite being handed his debut by Rafa Benitez as an 18-year-old. Philippe Coutinho has starred for Liverpool since moving from Inter Milan in 2013 . The Brazil playmaker has been nominated for the PFA Player of the Season this term . Speaking to Sky Italia, Ausilio said: 'He was just 18 when he arrived at the club from Vasco. '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.'
