“I still maintain that a top class striker should be high on the agenda this summer and I do think that if I was in Brendan Rodgers’ position then I would be looking to pair Griffiths with someone else up front,” the Celtic legend wrote in The Glasgow Evening Times.
“Steven Fletcher is out of contract and has been linked with Celtic – again – and although I am not sure how much substance there is to those reports, a player of that calibre and at that level is the right direction to head in.”
The Scotland international striker, though, has claimed that the Scottish Premiership champions have not made any contact with him.
The 29-year-old former Burnley and Wolverhampton Wanderers man has been linked with a move to Celtic in the summer transfer window, with The Sunderland Echo recently claiming that the Bhoys are his main suitors.
"I don't know, they obviously have a new manager (Brendan Rodgers) so that is up to him,” Fletcher told Sky Sports when asked if the time was right for a move back to Scotland. "But I haven't had any contact with Celtic.
"I know everyone likes to think I have, even in recent times when I have been linked with them there has never been any solid connection with me and them.”
Fletcher is not a very prolific striker, but he is a decent footballer who would be a good signing for Celtic.
The former Hibernian striker would come on a free transfer, which would be beneficial for the Bhoys as they would not have to pay any transfer fee.
