Dick Advocaat and Sunderland parted ways on Sunday after failing to lead them to a single victory to start the season.

Advocaat told Studio Voetbal: "I already made my decision last week, but the club asked me to do the match against West Ham and I really wanted to finish this in style.

"The struggle against relegation is not my cup of tea. I think it was time for someone else to take over at Sunderland. I became negative and that didn't feel like myself.

"I don't regret signing my new contract because it was a great experience. Our squad was simply not good enough. The club knew we had to strengthen ourselves, but the chairman [Ellis Short] never told me how much we could spend."
