Former Celtic captain Tom Boyd believes recruiting a top-class goalkeeper is the club's priority ahead of the new season.[LNB] Fraser Forster proved to be a hit at Parkhead last term but his loan spell looks unlikely to be repeated after Newcastle boss Alan Pardew criticised the standard of the Scottish Premier League.[LNB]Out-of-favour Manchester City goalkeeper Shay Given has been linked with a move to the Hoops and recently admitted he would not rule out a switch to Glasgow, but finances could prove to be a stumbling block for Neil Lennon.[LNB]Boyd said: "Shay has plenty of experience. He's not been getting a game at Manchester City and someone of that ilk would be fantastic, with the ability that he has.[LNB]"It depends on the financial situation and what his wages are. We will wait and see.[LNB]"A goalkeeper is probably the priority for Celtic, whether it be Fraser Forster again or somebody else. Someone of that stature would be a great asset to the club."[LNB]Boyd would also love to see Lennon add to the outfield players he already has at his disposal over the summer but does not believe a big-name signing is vital.[LNB]He said: "A marquee signing would be nice but it's whether they can add to the team.[LNB]"We've certainly had a few of them down the years and some of them have not worked out.[LNB]"When you look at Neil's record in the transfer market, it has been very, very good.[LNB]"Kris Commons, Beram Kayal, Emilio Izaguirre - these lads have all come in and made a massive impact.[LNB]"None of them would have been regarded as marquee signings so if we can find more of that and add that kind of quality to the team, then I don't think we will be too far away next year."[LNB]Celtic will be keen to wrest the SPL title from rivals Rangers, who will be aiming for a fourth consecutive championship next term.[LNB]But Boyd believes it is impossible to say which half of the Old Firm are favourites for honours in the new campaign.[LNB]He said: "It's a toss of a coin. Rangers, at this moment in time, still have all the players who won the league championship last season.[LNB]"So nothing has changed. They finished the season on a high. Time will tell."
