Born in Paris, France, N'Diaye began his career with US Vandœuvre in Vandœuvre-lès-Nancy. At the age of 14, he moved across the arrondissement to join the biggest club in the region, AS Nancy. Upon arrival, Alfred endured early struggles, but quickly gained noticed following his second season at the academy. In 2006, he signed his first professional contract.
N'Diaye made his debut in the squad during the 2007–08 season in the Coupe de la Ligue, at the age of 17, coming on as a halftime substitute for Frédéric Biancalani in a 0–3 loss to Lens. That was his only appearance that season as he would be relegated back to the reserves helping a young Nancy reserve squad barely avoid relegation.
Following the season, N'Diaye earned promotion to the senior squad for the 2008–09 season. He was assigned the number 29 shirt and made his league debut in the opening match of the season against Lille appearing as a substitute in a 0–0 draw. Two months later, he earned his first league start in a 1–1 draw against Paris Saint-Germain. His positive play earned him regular starts in the squad, including playing the full 90 minutes in the club's 3–0 upset victory over Olympique de Marseille at the Stade Vélodrome and playing, on two occasions, 120 minutes of football in cup play against Grenoble in the Coupe de la Ligue and SO Romorantin in the Coupe de France. In total, he made 27 appearances and collected 7 yellow cards.
On 1 July 2011, Nancy confirmed on its website that the club had reached an agreement with Turkish club Bursaspor for the transfer of N'Diaye. The deal was finalised on 3 July for a reported fee of €2 million.
On 9 January 2013, it was announced that Sunderland had completed the signing of N'Diaye for a fee reported to be €4.7 million. He will be given the number 4 shirt. On 12 January 2013, N'Diaye made his Sunderland debut at the Stadium of Light in a match which they won 3–0 against West Ham United. He came on as a substitute for Adam Johnson and almost scored with his first touch in English Football as his shot went just wide. His first full debut for Sunderland came against Wigan away, in which he produced a fantastic assist for Steven Fletcher to score and put them in front.
Despite making a promising start to his Sunderland career, which saw N'Diaye put in a number of impressive performances even under managerial changes and facing the threat of relegation, On 28 July 2013 it was announced N'Diaye would join Turkish club Eskişehirspor on a season-long loan. On 28 January 2014, Eskişehirspor announced that N'Diaye's loan had been terminated by the club.
