Former Celtic striker John Hartson reckons "the writing is on the wall" for out of favour winger Luis Palma at Parkhead.

The Honduran has been the subject of transfer rumours recently, with reports yesterday claiming the 24-year-old could be en route to the MLS as early as next month.

Palma appears to have dropped out of manager Brendan Rodgers' matchday squad altogether, adding further fuel to the fire with regards to talk of the player's departure.

Speaking on Go Radio (via 67HailHail), Hartson said: "If Palma goes they will certainly want to get another one in over on that left-hand side. It is looking like the writing is on the wall for Palma at Celtic.

"It’s in the papers every other day that he is not happy and his dad has been quoted saying this and that. I just feel that if they get the right type of offer in January, I think they might act on that."

Hartson added: "I don’t think he’s done enough either. I think he has played in fits and starts. Sometimes he likes to play and does something really, really special and you think ‘Wow he’s back and is a good player, take it onto the next game’.

“He flatters to deceive a little bit. When he is one-on-one he tends to cut inside and pass it into midfield.

"You want to get a defender or opposing player in a situation with someone like Palma to run at him and make something happen.

"The amount of times he turns back, but then again in the following he might do something very good and you think he’s got something."
