Mourinho 'concerned' after United's latest defeat

Jose Mourinho's honeymoon period at Manchester United didn't last long.

The former Chelsea manager appeared to have revived the club after United finished August with a perfect record under Mourinho.

However, on Sunday, United suffered its third successive loss when Watford snatched three points away from the visitors, leaving Mourinho concerned about his team's poor form and recent lack of luck since Manchester City pulled off a critical derby win.

"I’m always concerned when we don’t get the result we want," Mourinho told BT Sport.

When asked about Watford's opening goal where Miguel Britos appeared to foul Anthony Martial before setting up goalscorer Etienne Capoue, Mourinho avoided blaming match official Michael Oliver, and instead, cited his side's lack of luck.

"The referee and linesman’s mistake is not under my control," he said. "I can’t do anything to improve it and, in the second half, we were much better. We got the equaliser and, after that, we were the team (pushing for a winner). (Heurelho) Gomes makes a phenomenal save and the luck is against us, something we cannot control."

The defeat follows United's disappointing 1-0 loss in its opening Europa League tie against Feyenoord earlier in the week. United has not recorded a win since beating Hull City on Aug. 27, just days before the international break.

United will have a chance to get back into the win column when it visits Northampton Town in the League Cup on Wednesday.
