Neil Lennon has hinted that Celtic could end their interest in Wolves striker Leigh Griffiths.

Celtic went 18 points clear of Aberdeen at the top of the Scottish Premiership on Wednesday night with a 4-0 home win over Kilmarnock but have suffered frustration after having two bids rejected by League One's Wolves for the 23-year-old Scotland international.

The door appeared to open for the move to be completed when Wolves confirmed on their official website they had reached agreement with Coventry City for the transfer of Leon Clarke, with the 28-year-old striker "undergoing talks and a medical with a view to completing a permanent move."

However, after watching goals from Joe Ledley, Charlie Mulgrew and substitute Amido Balde - and an own goal from Killie defender Lee Ashcroft - extend the Hoops unbeaten league run to 23 games, the Celtic boss was playing it cool with regards Clarke's possible move paving the way for Griffiths to come to Parkhead.

Lennon said: "It may do but we will see what tomorrow and Friday brings.

"There is no further movement either way.

"The fee was rejected so whether we go back again is something we will have to consider over the next couple of days.

"I don't get involved in that (fee), Peter (Lawwell, chief executive) does that side of things but I will speak to him tomorrow and see where we go.

"We are looking at other options as well.

"I am not saying the deal is dead by any means but we do have other people in mind, not for that particular position but also for other positions."

Another clean sheet from keeper Fraser Forster meant the champions equalled the club record of 10, last achieved in 1921/22 and the England cap was given a round of applause by the fans at the end of the game.

Lennon said: "He made a terrific save at 2-0 and he has done that in the last two or three games,

"He is another player in superb form and thoroughly deserves all the accolades that will come his way.

"It is a fantastic achievement and we are hoping to keep that run going if we can."
