Le Bris reacts to Sunderland's win at Derby

Sunderland head coach Regis Le Bris spoke to BBC Radio Newcastle after the Black Cats beat Derby County 1-0 at Pride Park.

"I don't know, really [about why Isidor's goal was disallowed].

"Maybe with VAR we could analyse the first ball and maybe an offside, but I don't think it was that decision. It was higher up the pitch and at the moment we don't know.

"It could have changed the outcome of the game, but at the end it was another tough game and the balance was different for the duration.

"We started maybe a little slowly because they are direct, and then after 15 minutes were good and created many chances in the first half. And if you don't score the second goal, you know that the opponent will believe until the end and it happened like that.

"It's good for our character because it shows that even in these circumstances we are ready to defend until the end.

"I'd also like to have a more relaxed end to the game because it's important to avoid last-minute equalisers, and we have had them before."
