Sol Campbell is ready to ignore more lucrative offers from other Premier League clubs and sign a one-year contract at Arsenal, having convinced Arsène Wenger, the manager, that he merits a new deal at the club.

Wenger has decided that he wants to keep the 35-year-old centre-half, after watching him produce a commanding performance at Tottenham Hotspur last month. Campbell has maintained his form in Arsenal's three subsequent games and he hopes to finish the season in fine personal style against Fulham on Sunday, before sitting down with the club to commit his future.

Campbell had previously struggled for Arsenal, whom he rejoined on a short-term contract in January, having not played top-level football since last May. He had left Portsmouth for League Two Notts County over the summer, only to walk away after one appearance.

But the game at Tottenham, one of his former clubs, for which he was fiercely motivated, marked the turning point and Wenger has resolved to reward him, mindful also that his experience and influence in the dressing-room are important.

Wenger looks increasingly likely to lose one of his first-choice centre-halves, William Gallas, on a Bosman free transfer because the club cannot agree a new contract with him. Mikaël Silvestre, meanwhile, is expected to be released when his deal expires at the end of the season and to lose Campbell as well would gravely weaken his central defensive options.

Gallas, who has missed the end of the season because of a calf injury, has held out for at least a two-year contract extension only for Wenger to offer him one year, with the performance-related option of a second. Gallas has grown increasingly disillusioned and he is likely to leave, with Paris St-Germain, Gallas's home-town club, favourites to sign him.
