Sunderland were said to be 'stepping up' their bid for the right-back.

Rumoured Sunderland target Jason Naismith has signed for Peterborough United.

The Sun on Sunday claimed Sunderland were 'stepping up a bid' for the 23-year-old - who played under the new Mackems manager Jack Ross at St Mirren - and were looking to offload players ahead of a '£200,000' move.

However, it is Peterborough who have won the race for his services - although, according to Posh owner Darragh MacAntony, a 'massive EFL club' did come close to derailing the deal.

Posting on Twitter on Tuesday evening, MacAnthony wrote:

Naismith impressed despite Ross County's relegation last season, attracting interest from Aberdeen, Burton Albion and Plymouth, according to the Daily Record.

And the signing looks even more impressive for Peterborough, with MacAnthony suggesting the Cambridgeshire side have a future Scotland right-back on their hands.

Sunderland released their long-serving right-back Billy Jones last week, but still have Donald Love and Adam Matthews on the books in his position.
