SUNDERLAND will make a renewed approach for Freddie Ladapo after the Plymouth Argyle striker’s proposed £500,000 move to Portsmouth collapsed.

Both Sunderland and Portsmouth made a move for Ladapo earlier this month, but the 26-year-old’s initial preference was a move to Fratton Park as it would have enabled him to remain closer to his current base in the South-West.

Portsmouth officials agreed a fee of around £500,000 with their counterparts with Plymouth, and Ladapo’s representatives are understood to have held talks with the Pompey hierarchy.

However, those talks have broken down over financial issues, and Portsmouth, who are close to agreeing a deal for Aberdeen forward Gary Mackay-Steven, are understood to have withdrawn their interest.

That could prove to be a bargaining ploy, but Sunderland’s recruitment team are aware of the developments and are pondering another approach.

Jack Ross is keen to strengthen his forward options this summer, and has identified both Ladapo and Doncaster Rovers forward John Marquis as leading targets.

The Black Cats boast Will Grigg and Charlie Wyke as their current attacking options, but neither forward proved prolific in the second half of last season. Duncan Watmore is another alternative in the attacking positions, but the injury-plagued 25-year-old is on high wages and could be deemed surplus to requirements if a club came in for him.

Ladapo scored 18 league goals for Plymouth last season, but is expected to leave Home Park after his efforts proved insufficient to keep the Pilgrims in League One.

Sunderland have also held discussions with Rotherham United about winger Jon Taylor, but face competition from a number of Championship clubs for the 26-year-old, who is available on a free transfer.

The Black Cats are seeking a replacement for Lewis Morgan, who has returned to Celtic after his loan spell expired, and have identified Taylor as a financially-attractive option.

The 26-year-old made 30 Championship starts last season, scoring four goals, but has turned down the offer of a new deal at the New York Stadium in the wake of Rotherham’s relegation to League One.

Sunderland are ready to offer a deal, but alternative interest from Luton Town and Barnsley, both of whom were promoted to the Championship last season, could scupper their hopes of completing a transfer.

Meanwhile, Sunderland have advertised the naming rights for the Stadium of Light via a promotional video on the social networking site LinkedIn.

The Black Cats have been seeking a stadium sponsor for a number of months now, with a betting company and an energy firm linked to a possible tie-up.

Mark Moisley, the club’s head of revenue, has posted the promotional video, which boasts of Sunderland’s worldwide exposure on Netflix and the success of concerts such as the recent gig by the Spice Girls, on LinkedIn and sent it to potential partners.
