"It's a pity because he's a player with a lot of good skills and he's in a position where there is still a lot of growth," Corberan said. "He is in a growing process but he isn't going to be just ready with game minutes. It's part of this.
"We have players who went on loan to places where we wanted them to play, and they didn't, Reece Hall (to non-league Hereford), we sent him on loan and he has come back because he didn't play, but part of his development is to have the experience where you're not playing.
"It helps you to mature, and helps you to grow. You don't grow only when you play, you grow when you adapt your resources to the demands.
"Some players have the experience, they have used this time, this process and they've brought these things with them when they've needed to compete. Other players still need to grow when you are 17,18,19 years old and you go into one level of the Championship, to a club like West Bromwich which is in a good position in the table, you cannot go there in your first loan thinking this is under-21 level.
"He knows this. I remember in the first notes that he put in the club, he was very conscious of this it's a process that he needed and wanted to do.
"At West Ham, he trained six times with the first team. The other parts were with the 21s. They're competing in the same league as our 21s and how many players from our under 21s are in our squad? Only in the cup we did."
