St Mirren have signed Manchester United and former St Johnstone midfielder Matty Willock on a season-long loan.

The 21-year-old midfielder made 12 appearances for the Perth Saints in the second half of last season.

"He certainly brings a physicality to the midfield," manager Alan Stubbs said.

"Most importantly, he brings competition for places.

"He is a big lad, six foot one or two, powerful, aggressive, he will get around the pitch.

"He is a threat in terms of scoring, which is what I want to add to the midfield area, and he certainly gives us a lot of options in there."

Wllock told the St Mirren website: "I know what I am coming into. I know the tempo of the game is really quick so hopefully my experience last season stands me in good stead."
