Charlton have made an official approach for manager Chris Wilder, his current club Northampton Town have confirmed.

Jose Riga resigned as head coach of Charlton on Saturday following the final Championship game of the season.

The Belgian joined the club in January in a bid to keep the Addicks up, but failed to repeat his heroics from two years ago.

As Charlton search for a new boss, League Two champions Northampton have confirmed the club received an official approach this morning to speak to Wilder and assistant boss Alan Knill.

Chairman Kelvin Thomas said: “As is common knowledge I have an excellent relationship with both Chris and Alan, and we as a club and myself personally would obviously be very sorry to see them go.

“We had already begun discussions about much improved new deals, but I think it is fair to say we would not be able to match both the salary and the playing budget for next season that a club the size of Charlton could offer.

“We have known for a while that Chris and Alan would be targets due to the fantastic success they have achieved, and together we have already turned down some interest from other clubs, but after discussions this morning I respect their decision to meet Charlton.”

Chris Wilder added: “My relationship with the Chairman and the fans is going to make this a very difficult decision, but I do feel at this stage of my career it is one I need to explore.”
