Clark predicted that the West Ham United midfielder will relish the platform provided at St Andrew’s.
“Why sign him? Because he’s a fantastic talent,” Clark told the Birmingham Mail.
“It’s been well documented by people more in the know than myself that Ravel is one of the best, if not the best, to come out of the Manchester United Academy.
“What he needs to do is get playing on that pitch, start enjoying his football and showing everyone the ability he has got.
“Certainly, in the mould we are playing, Ravel will fit in and I am sure will excite our supporters very much.”
Clark added: “I remember seeing him playing against Huddersfield Town’s youth team when he was 15, 16. He was an unbelievable talent, and I’ve always kept my eye on him since.”
