"I like Enner as a player and when I was coming to the club I marked him as one of our key players," Bilic told the club's official website.
"I rate him highly - and he knows that. His last season was not ruined totally but damaged by a couple of big injuries.
"We've got some new players there, he wanted to go and I think it's a very good one for both [the club and the player].
"Sometimes the best outcome is to cut it and start a new beginning. Although it's a loan - that could help him and that could help us long-term as well."
