Celtic forward Leigh Griffiths has described his teammate Moussa Dembele as "one of the top young talents in Europe".

Dembele scored his 15th Celtic goal of the 2017-18 campaign against Rangers in the semi-finals of the Scottish Cup at the weekend.

Griffiths has branded Dembele's performance against Rangers "unplayable" as the Scot paid tribute to his 21-year-old teammate's 'calmness'.

"With that display, Moussa showed he is one of the top young talents in Europe," Griffiths told Celtic's official website. "He bullied their centre-halves and he was unplayable, and his penalty just summed the guy up.

"It doesn't matter how big the occasion is, he is always calm. I thought he was exceptional. He never gave the Rangers defence a minute's peace. He has that in the locker and when he is in the mood like that he is a joy to watch."

Dembele joined Celtic from Fulham in the summer of 2016, and managed 32 goals in 49 appearances during his first season with the Scottish giants.
