Brann Bergen striker Thorstein Helstad is waiting for Everton to make a concrete offer for him.

Helstad said: "I haven't heard anything official since Everton in January.

"It is a possibility to play abroad again, but I like it very much at Brann at the moment."

The 30-year-old is the second top scorer in the Tippeligaen with five goals in eight games.

The experienced hitman, is under contract in Bergen until late 2009.

But his agent Stig Lillejord last night confirmed Celtic are watching him closely. Lillejord said: "His form makes it natural that the interest in him has increased. One of the clubs that have watched him most times is Celtic."
