“If £13m is the fee for someone who’s played a few games then obviously it’s quite unusual but the transfer fees have gone right through the ceiling anyway so you should never be surprised with anything in football.
“It is an awful lot of money and it will be well spent if he realises his potential. He’s got a good chance of becoming a very, very good player.

German move good for Burke – McFadden
Meanwhile, James McFadden, who won 48 caps for Scotland between 2002 and 2010, believes the move to Germany will benefit both the player and the national squad.
“He’ll learn a new culture and develop in a good way, hopefully, for Scotland,” said Motherwell player-assistant manager McFadden, 33.
“Going over to a different country and learning a new way of playing the game will be great for his development.
“He’s got a great physique and he looks as though he’s got all the attributes to become a real top player. The fact that he’s made the move at such a young age will tell you all you need to know about him.
“[RB Leipzig] will be hoping to challenge for the [Bundesliga] title because of the ambitions they’ve got. When players are doing well in Germany, Bayern Munich will snap them up, so that’s got to be the next aim for him.”
