OXFORD United's summer transfer business has received an early boost with the signing of Marcus McGuane.

The midfielder impressed on loan from Nottingham Forest earlier this season and joins on a three-year deal for an undisclosed fee.

McGuane is still working his way back to fitness after suffering a thigh injury in United’s 2-0 win over Bristol Rovers on January 23.

The 22-year-old was just getting into his stride and is aiming to pick up where he left off.

“I’m very happy,” he said.

“Over the last three to four years this is the happiest I’ve felt playing football, so I feel like it only made sense for me.

“There’s a lot more to come from me.

“I feel good here, I feel comfortable, so I feel like I can get my best football and just carry on where I started.”

The former Arsenal and Barcelona man found game-time limited at his previous clubs, but made 21 appearances for the U’s in the first half of the season.

He had become an influential part of United’s midfield before suffering the injury, although he warned his recovery is far from over.

McGuane said: “It feels a lot better, I’ve probably got another two months so I probably won’t be fit until pre-season.

“It came at an annoying time, but it’s one of those things.”

Head coach Karl Robinson has said on several occasions he feels United have lacked power in midfield during McGuane’s absence and revealed last month he wanted to bring him back.
