Cape Town - Watford winger Gerard Deulofeu admits it's his own fault for failing to establish himself as a regular starter during his time at Barcelona.
In January, the 24-year-old was sent on loan to Watford until the end of the season after Barca manager Ernesto Valverde deemed him to be surplus to requirements at Camp Nou.
Deulofeu, who has over a year left on his Barcelona contract, believes it would be tough to return to the Catalans after his loan spell and doesn't know where he will play next season.
"It will be very difficult for me to return," Deulofeu told Esports Cope.
"Barcelona let me leave on loan because they do not have an interest in me while I had not played in a long time – things were not working out and I was not happy sitting on the bench.
"Since joining Watford I have been very happy, they have treated me well and when I have been playing I have felt good.
"At the end of the season I will need to speak to Barca, to discuss things with my agent but I cannot say exactly what will happen because it is not all down to me.
"My failure there was my fault, I did not do enough to earn the right to start more games and I did not prove myself.
"Valverde gave me the opportunities but I did not take them."
