Mowbray on 'tough period' for West Brom

West Bromwich Albion manager Tony Mowbray believes his side are facing a "tough period" after losing 3-1 to Derby County.

Goals from Ebou Adams, Jerry Yates and Nathaniel Mendez-Laing, the Baggies' sole score coming from striker Adam Armstrong, subjected the Midlands club to their fifth loss in six games.

"Obviously, it's a tough period for us," said a dejected Mowbray to BBC Radio WM.

"I haven't seen anything since I've been here like the goals we conceded today from the set-plays.

"It's so unlike us. Two set-play goals from a hard-working, honest team. I thought we lacked courage today, didn't play enough forward passes, weren't brave enough on the ball."
