Hertha Berlin have confirmed they are interested in signing Celtic striker John Hartson.

Hartson’s future at Parkhead remains uncertain with his current contract due to expire in the summer at which time, the Welsh striker will be free to leave on a free transfer.

Hertha general director Dieter Hoeness admitted they have held talks with the player’s agent Jonathan Barnett about the possibility of moving to Germany.

“It is our policy never to discuss individual players but there is no doubt that we are interested in getting a new forward in for the summer,” Hoeness told the Daily Record.

“Our scouts are watching a number of possible signings and it is correct that John Hartson is a player we are looking at.

“We are now closing the fishing net in more and more.

“We started with a big list of targets and there are fewer and fewer names on it. But Hartson is still there.

“We have had talks with his agent in the last week but I can’t say any more than that. I don’t comment on intermediate results. Let’s just say that Hartson is a player we are following closely.”
