Sunderland handed chance to land free agent, Portsmouth star 'questions future', Ipswich given surprise boost - updates on Tranmere and Gillingham; League One and Two rumours

Dimi Konstantopoulos is now officially a free agent

When the Dutchman's departure was confirmed earlier this month, one of the first names to come to the front was the experienced Dimi Konstantopoulos.

Now, the Black Cats could have a free hit at bringing the 40-year-old to the Stadium of Light after he was released by Middlesbrough on Tuesday.

That is, of course, if Jack Ross holds a genuine interest in Konstantopoulos, which the Northern Echo suggested was true a few weeks ago.
