The Spain international was sent to Leverkusen by the Manchester United manager during his time at the club, and believes he was ready for first-team football
Real Madrid defender Dani Carvajal has criticised former coach Jose Mourinho for restricting his chances at the Santiago Bernabeu.
Carvajal seemed ready to make the step into the senior side at Madrid in 2012 after impressing at their reserves the previous two seasons, but Mourinho decided different and sanctioned the right-back's exit to Bayer Leverkusen instead.
The Spain international - who misses Euro 2016 due to injury - returned to the Bernabeu after just one season as Madrid exercised their buy-back option, but Carvajal has not forgotten about the lack of faith shown in him by Mourinho.
"I felt that I was perfectly ready to play for the first team, but hey, the coach, Mourinho in this case, did not have me in his plans," Carvajal told Marca.
