Marcus McGuane has left the U’s for Sky Bet Championship rivals Bristol City, heading to Ashton Gate for an undisclosed fee.

United must comply with the 25-man squad rules in the Championship, with all that finalised upon the window slamming shut a week today.

U’s head coach Buckingham anticipates that exits over the next few days will more likely be loans, as he offered an update on the club’s work in the transfer market.

Buckingham said: “We’ve had a plan for what we want from this window, and that isn’t complete yet.

“Marcus is the first high-profile outgoing since the end of the season. We’ve got a plan and we’re still working hard towards that plan.

“There’s a 25-man squad you can register when the window closes, so we’re aware of that, and the conditions that come with that.

“We’re aware of that and working towards that, and the last thing we want is having too many players here, as it affects the budget, but also it’s about making sure we get the players in that we need, and that we don’t leave players in a space where there potentially is no football for them.

“We’ll see a bit more movement in the outgoings, more so with the loan market. It’s important we have our players out if they’re not playing here, from a development point of view certainly. We need to see what we get in the building first.

“There’s still an opportunity to bring people in, and we’re still trying to stick to that plan.”
