Robert Green's future at Norwich City has been plunged into doubt after his agent said he would welcome a move back to the Premiership with Portsmouth.

Robert Green's future at Norwich City was plunged into doubt last night when his agent said he would welcome a move back to the Premiership with Portsmouth.

Pompey manager Harry Redknapp is in the hunt for a new number one and is rumoured to have turned his attention to Green after failing in an attempt to lure Chelsea's Carlo Cudicini to Fratton Park. It is understood there has been no contact between the two clubs over a possible move and it remains to be seen if Redknapp follows up his interest with a firm bid.

But Green's representative Andy Evans is clearly hoping they can come to a mutually acceptable agreement before the end of the January transfer window.

“Portsmouth have an interest in Robert and if the two clubs can agree a free then he would be interested in resuming his career at the highest level,” he told Sky Sports last night.

Green, whose current contract expires at the end of next season, has emerged as one of the top goalkeepers in England since making his debut for the Canaries against local rivals Ipswich towards the end of the 1998-9 season.

He has now made a total of 227 appearances for the club and hasn't missed a game through injury for nearly four years although, ironically enough, he is a doubt for Saturday's trip to Plymouth after a painful clash with Marlon Harewood during last weekend's FA Cup tie against West Ham.

Green was linked with a number of top flight clubs following Norwich's relegation last May but, with few vacancies up for grabs, a big money move never materialised.

It was always likely that the speculation would resume once the transfer market reopened for business at the beginning of the month, and so it proves with Everton as well as Middlesboro looking for a new keeper and Middlesboro also likely to be in the market soon should Mark Schwarzer get the move he has requested.

Portsmouth are the first of Green's admirers to show their hand this time and with his agent apparently happy to talk up a move it's clear there's a very good chance of the player moving to the south coast over the next couple of weeks, providing a satisfactory deal can be struck.

Norwich manager Nigel Worthington is understandably keeping his valuation of Green close to his chest so putting the price tag on the player is pure speculation.

But the fact that another top championship keeper, Southampton's Antti Niemi joined Fulham in a £1.5million deal this week would appear to give a rough idea of the likely fee.
