N'Diaye is still settling into life in the Barclays Premier League since his January move from Bursaspor and O'Shea can only see him getting better and better.
"When he [Alfred] first came to the club we knew he was going to grow into the role and he's going to get stronger and fitter and more used to lasting out the full 90 minutes," the stand-in skipper explained to safc.com.
"He's going to go from strength to strength.
"Also the organisational side of things is really helping him grow and become a stronger player for us - you saw he's able to hold the ball up for us, break away down the wide areas and really kill the game for us.
"He's going to pop up with a few goals as well."
