Ryan Mason does not want to see repeat of West Brom display at Millwall and pointed to lack of character and quality

The Baggies head coach said his side's blunt performance at The Den - with one tough-to-recollect shot on target - was their worst of the season and his tenure so far.

Mason said Albion were second-best in every department throughout against the Lions and did not earn the right to play any sort of football on a day where the physical hosts ran all over and bullied their visitors in the swirling wind of Storm Amy.

Big defender Jake Cooper handed the hosts a lead by the interval and Millwall, who were coming off a woeful 4-0 midweek home defeat to Coventry, struck twice in the second period through Femi Azeez's rocket and Zak Sturge's third.

Mason, whose side started the day fourth but dropped to seventh with a first away defeat of the season, admitted it was the first time he had felt his Albion side were a long way second-best.

Mason said: "We were well below-par in every aspect of the game. We didn't deserve anything from the match, so it was a difficult afternoon for us.

"Yes, I think it's our worst performance, absolutely. I think every element of the game they were better than us at.

"It's the first time it's happened this season where I've really felt that, so it's tough, it's disappointing, and the players feel it as well, most importantly. So we got what we deserved today."

Mason made four changes from the side that won 1-0 at Norwich on Wednesday night. One was enforced with left-back Charlie Taylor missing through injury.

But the visitors were beaten to every ball across the park with defenders unable to cope with wave of Millwall's attacks, many from set-pieces, and attackers struggling to get into the game at all, with most totally anonymous.

The 2,000 travelling supporters were irked at what they had seen and many left long before the full-time whistle in south east London.

The visiting head coach said his side lacked personality and quality.

"I just think we probably didn't show ourselves anywhere near what we needed to do to get anything from this game," Mason added. "I think when we had the ball, we were below-par.

"I think this type of game in the conditions, with the wind, with the dry pitch, you need to show personality and quality, and we didn't quite have enough today.

"We gave away far too many free-kicks, far too many set-plays, invited pressure on our box, the ball kept coming in, and it was really, really disappointing, because we felt like as the game went on the space would open up but we just didn't earn the right to get to that point in the game where we were still in it.

"They were better than us and we need to try and avoid that type of performance again."
