It's reportedly back to square one for Feyenoord after failing to land Seny Dieng from Middlesbrough. The goalkeeper had been in their sights for weeks, but despite talks taking place over a potential transfer, the move never materialised and it looks like they will need to move onto fresh targets. He'll remain with his current club for the time being - unless an improved bid is made. Negotiations failed to produce a deal, and with no other reported suitors, the situation is set to remain unchanged for Seny Dieng. Across the season 25/26, Feyenoord have let in 32 goals in 21 (1.52 per game), roughly in line with the Eredivisie average. Seny Dieng would be expected to give them some extra stability and depth for the tougher stretches of the season. Middlesbrough have also been linked with Joe Wildsmith while Feyenoord are reportedly monitoring Mats Deijl, Joshua Kitolano and Jeremiah St. Juste. Need more Feyenoord transfer rumours?
