"We had great fun in the locker room and tried to get out on to the pitch to bring the cup to the fans, but they had already gone," he said of the chaotic pitch invasion that forced players back into the tunnel.

"We are a strong squad and perhaps the only thing we were lacking was that victory. We hope this success can help us build next season."
