Gueye has played for his country in a central midfield role.
Earlier in the season, David Moyes said: "We're not nailing him down in any particular role at present.
"We're still finding the way we think will be best suited to him."
First team coach Jimmy Lumsden was also excited by Gueye's livewire pre-season performance against Moyes' former club Preston North End, said: "Gueye's a good talent.
"He's quick, he's got a great first touch, and I think he's going to be able to play in a few positions."
