The managers
West Brom's Carlos Corberan:
“Bristol City and us are the teams that are suffering in this period.
“Teams like Derby are going to play four games in a row – we're going to play five. They have a week to play on Thursday, while we only played on Sunday.
“It's a physical handicap. It is madness. It is unfair to play against a team at this time of the season that has got two extra days back.
“We can't say we're not going for results, it's up to me but it's too much.
“Five games in a row. We shouldn't have played today, knowing the upcoming games. We should have played on Saturday, like the other teams in the competition.
“We only have three days between them and it will be difficult from a physical point of view. That's how it is.”
Bristol City's Liam Manning:
“The best team definitely won, they were better than us. We were a bit passive at times, caught between pressure and obstruction.
“That's the problem when you disconnect. The chance came from counter-attacks. When they turned it over they were very quick from their box to our box. We have to be better and I look at myself first and foremost.
“They're well organized defensively, it's a tough place to come. We didn't get into enough areas. We ended up getting picked off.
“We have to respond on Boxing Day now. We have to win more games, it's as simple as that. At the end of the day we are in the results business.
“We have to start winning games, you don't want to move and go too far without him. If you want to push forward you have to get consistent results and we didn't do that enough.”
