West Ham United are believed to be interested in the pair, as they look for new additions this summer.
The pair are very differing players, but they could combine to create a brilliant midfielder partnership at West Ham.
Stoke may have been relegated over the past season, but Ndiaye actually impressed after joining in January.
The Senegal international offers pace and power, and would be an upgrade on Cheikhou Kouyate for Pellegrini’s side.
Cairney, meanwhile, could operate as a controlling presence in the West Ham midfield.
The Scottish international is one of the leading talents in the Championship, and has impressed all campaign.
Cairney would surely force Mark Noble out of the team at the London Stadium, if he was to join.
And the potential of seeing Ndiaye and Cairney working in tandem next season should be an exciting prospect for West Ham fans.
