Williams is equally comfortable on the left flank or in the centre of midfield.

Welcoming the signing, Harps boss Paul Hegarty said: "Shaun will be a great asset to us because he gives us an extra option. He can play on the left-hand side or in the centre of midfield."

"He's an exceptionally talented player and he'll be a good player in our team. He looks after himself very well and he has a great attitude to the game. "We would be hoping to have him for the whole season. He is initially here until the next transfer window, but it is with a view to making it a season-long deal."

Williams' switch to Finn Park will see him become the sixth new face at first-team training, as he will join up with Gary Beckett, Marc Mukendi, Gerry Gill, Stuart Malcolm and Cornelius Gallagher, along with his other new team-mates next week.
