The 32-year-old defensive midfielder is on the verge of signing a new deal according to quote attained from his agent who says the club, player and representatives are '99% of the way there'.
Diao played 21 times last season, to take his Potters total to 62 appearances, but struggled, as in previous seasons, with injuries and was never fully fit.
It looked like the ex-Liverpool star, who earnt an international comeback last season, was on his way to pastures new after saying we was willing to listen to offers fdrom other clubs at the end of the season but this latest twist means we will probably see him for another 12 months.
How much Diao contributes to the 09/10 season may not fully be known to supporters as his presence in the dressing room, whether playing or not, is said to be one of huge importance, especially with his fellow African players.
