Millwall boss Neil Harris is sorry to be losing Darko Gyabi to Manchester City.

Gyabi, 14, joins City for a fee rising to £1m.

“As the manager of the football club, you want to see the opportunity for your young players to thrive, but it's very difficult in the modern game to keep players who have their heads turned by huge, world-renowned club," Harris is quoted by News at Den.

“Man City are that huge club. We talk about transfer fees for young players, and I find it very difficult. Dealing with players that have played 50, 60 international games, and then you're dealing with 13-, 14-year-olds. It's very tough.

“This is one that has been publicised, but loads of these go on through the course of a season at our club and everywhere else in the country and don't get reported.

“I've seen Darko play myself a couple of times and he's an exceptional young player. But when Man City come calling it's very difficult to make players want to stay.

“If players aren't going to stay then you have to make sure you get the best deal for the club.

“We wish Darko all the best for the future and we hope to see him on the big stage one day."
