Adam Claytons’s £1.5m move to Middlesbrough from Huddersfield Town is expected to quickly get the green light.

Personal terms on a three-year contract for the 25-year-old midfielder are already in place, along with an agreement on a transfer package between the Championship rivals.

Now, all that’s needed are the results of the medical the former Manchester City and Leeds United player took at Boro’s Rockliffe training ground – and those are expected on Wednesday morning.

Both clubs appear keen to get the deal done and dusted and sources in Middlesbrough suggest manager Aitor Karanka is keen to get Clayton working with his squad ahead of a debut against Lee Clark’s Birmingham City on Saturday.

While the fee agreed is £1.5m, appearance cash and promotion bonuses could mean Town received over £2m for a player they bought for just £350,000 from Elland Road two years ago.

Clayton did not figure for Town in the friendly against Newcastle United for what the club reported to be a dead-leg niggle, although he did play for 80 minutes last Saturday in the defeat by Oldham Athletic at Boundary Park.

Boro have been chasing Clayton since last year. The player would have been out of contract with Town at the end of this season and would have been able to walk away with nothing.

Now, when the expected deal goes through, John Smith’s Stadium boss Mark Robins will have leeway to bring in the fresh faces he is targeting before the transfer window closes at the end of this month.

He is being linked with interest in Boro midfielder Jacob Butterfield – who he worked with at Barnsley – and Robins is also considering making an offer to defender Sean St Ledger, who is a free agent, has been training with Town and played the second half of the 2-2 draw against Newcastle, in which Jon Stead and Radi Majewski netted for Robins’ men.
