Stephen McManus says he is "bitterly disappointed" after Celtic's UEFA Youth League defeat to Feyenoord.

The young Hoops went down 3-0 in Rotterdam after goals from starlets Givairo Read, Jaden Slory and Antoni Milambo.

However, the B team coach feels there is plenty his side will be able to take away from the fixture. 

He told Celtic TV: "We are bitterly disappointed with the result. The first thing for us is the performance. We just lacked a little bit of belief at this level.

"It is the first game in the competition, the last two matches have been a brilliant learning curve for the boys because they have never experienced that feeling before.

"We have played West Ham and Feyenoord and the boys will be better for it. We will be better prepared for it as a group and as individuals and we will do what we can to help the players.

"Our job is trying to produce players who can perform in our first team or have a career elsewhere.

"These games give the boys invaluable experience."
