Peter Lovenkrands is being tracked by English clubs

The Dane, who is out of contract in the summer, also revealed that he now refuses to go out in Glasgow alone.

Lovenkrands, who has scored 10 goals in eight games, told The Sun: "I've twice been hit by Celtic fans when going out having fun.

"If I want to go out, I never go alone. Most of the time I have one of my Scottish friends, Matt, with me."

Lovenkrands says he will only go out in public with his "minder" by his side.

"He is my Scottish shadow and he's helped me with good advice about where to go and not to go at certain times," he said.
