Sunderland are considering a move for Cardiff City defender Aden Flint, Football League World understands. 

Flint has been a regular starter for the Bluebirds this season, with the 32-year-old appearing 22 times in the Championship thus far. 

The towering defender has been operating at second-tier level for the last six and a half seasons, proving to be a tough opponent to come up against, whilst providing a threat from set-pieces. 

His aerial prowess has led him to score 27 Championship goals during his career so far, with four of those coming this season.

As well as possessing a wealth of Championship experience, Flint has also helped guide Bristol City out of League One back during the 2014/15 campaign.

The Robins possessed the best defensive record that season, whilst he netted an amazing 14 league goals in the process.

The Black Cats are hoping to break back into the Championship, and this season is shaping up to be their best opportunity yet, with Lee Johnson's men the current occupiers of second place.

However, Wigan Athletic have five games in hand and are a mere five points below the Wearside club, in an extremely competitive top end of the division. 

Sunderland appear to be casting their eyes over experience to help guide them back to the second-tier in their fourth attempt.
