Following a successful loan spell with Everton last season, Deulofeu had been expected to form part of the Barcelona squad for the new campaign.
However, the decision was taken to send the winger on loan to Sevilla for the 2014-15 season.
"The club must always look to get stronger. Deulofeu was my decision: I don't believe he would have got enough minutes to continue his devlopment. It's a coach's decision," Enrique told reporters.
"He needs to improve a few things and show he can be at a club like Barca."
