The 22-year-old said that he trained between “seven to eight” hours a day in order to make an early return to the starting line-up.
“I wanted to come back very early – it was my target,” Can was quoted as saying by SkySports.
“I spent every day here at Melwood, for seven or eight hours. I worked really hard with the physios and fitness coaches and I’m happy that I’m back. It was a target to come back for the second leg [against Villarreal].”
Can was initially expected to be ruled out until the end of the season but returned just three weeks after his injury to star in Liverpool’s win over Villarreal in the semi-finals of the Europa League.
The Germany international marked his return to the Premier League yesterday during a 1-1 draw with Chelsea.
The draw ensured that the Reds did not lose their final game of the season at Anfield. Liverpool take on West Brom next before the Europa League final against reigning champions Sevilla on 18 May 2016.
