A groundsman is called on to perform some crochet on one of the goal nets, which appears to be torn. As those repairs are carried out, a plane flies over the ground trailing a protest banner telling David Sullivan and Karren Brady to get out of West Ham.

Not long now: It’s a nice sunny Valentine’s Day in Staffordshire and the teams are out on the pitch in the compact Pirelli Stadium. West Ham are hoping to get the job done, Burton are hoping to make it to the fifth round for the first time in their history and kick-off is just a few minutes away.

Manager’s unconventional techniques are designed to bring fun as well as results and he has West Ham in his sights

“At times the players must think I’m bonkers,” says Gary Bowyer, the Burton Albion manager, volunteering the time he walked into the dressing room with a tennis racket and ball. It is one of the unconventional techniques he has used to convey his message and tap into their psyche. Every week he explores different themes and stories with his squad – be it bullfighting or UFC – and brings them to life through imagery and props, everything from dragons to toy tigers.

He has leaned into boxing and particularly Mike Tyson during an FA Cup run that has led them to a fourth-round tie at home to West Ham on Saturday. “The theme for this week is The Ultimate,” he says, referencing Tyson’s 1987 bout with Tony Tucker to become the undisputed heavyweight champion. “We’ve created this idea of climbing into the ring, the pitch, and away you go. We’re fighting West Ham and we’re going to have to take some blows. What do you do if you get knocked on to the canvas? Get back up or lay there and take it?”

Burnley have the chance of a Cup run, Leicester fear an unwelcome repeat and Brighton fans get a raw deal

Chelsea have kept two clean sheets in 10 games since appointing Liam Rosenior as head coach last month. Repeated doziness at the back has cost them. They have held commanding advantages against Charlton, Crystal Palace, Wolves and Leeds, only to give away silly goals. It is a bad habit and proved costly when a 2-0 lead was squandered during Tuesday’s draw with Leeds. Rosenior was livid afterwards, and is waiting for a consistent performance. Chelsea travel to Hull , Rosenior’s former club, on Friday night. They will surely advance against Championship opponents, but how they do it will matter. It is time for them to get serious.
