Sam Allardyce's nightmare start continues as League One Blackpool dump West Brom out of FA Cup

Sam Allardyce criticised his shootout flops after his nightmare start as West Brom manager continued with a shock FA Cup exit at Bloomfield Road.

Kyle Edwards, Darnell Furlong and Matheus Pereira all had their penalties saved by Chris Maxwell as Blackpool secured their first victory over a top-flight club in the competition for 45 years - since their 1-0 third-round win over Burnley in 1976.

Allardyce was furious that having seen his goalkeeper Dave Button save Jerry Yates first spotkick and Kamil Grosicky score Albion's first effort, his Premier League relegation strugglers then threw it away.

He said: "We should not have lost on penalties. I'm hugely disappointed with the ones we missed. Having saved their first penalty and gone 1-0 up we shouldn't have lost it.

"I expected us to play better and I didn't expect us to go behind twice. But at least I've some of the players I hadn't seen play and I'll be making a judgement on them."

The defeat was a huge setback for Allardyce who went into the tie having seen Albion lose three of their first four Premier League games by big margins since he took over from Slaven Bilic.

And it will add urgency to a major overhaul in the January transfer window with Allardyce, who has already signed Robert Snodgrass and Andy Lonergan and allowed Charlie Austin return to QPR, admitting: " I hope to be extremely busy in the window."

Allardyce made seven changes from the team thrashed 4-0 by Arsenal but his hopes of building some confidence and momentum with a victory over the club where he launched his managerial career in England in 1994 were dashed.

It was a memorable day however for Blackpool, managed by former Liverpool Under-23s coach Neil Critchley, and few could argue a team 13th in League One did not deserve the victory thanks to shootout hero Maxwell who had only just returned to the team after missing two games with Ccronavirus.

They twice led their Premier League opponents and Albion's second equaliser was from a harshly awarded penalty. And Critchley's determined side were the more energetic and threatening team in extra time before the shootout drama.

A delighted Critchley said: "It was a top performance from all of our players. We more than matched a Premier League team.I thought it was a deserved victory. But I was worried when it went to penaltiers because our record in shootouts this season hasn't been good."

Had Conor Gallagher not squandered Albion's best first-half chance - sliding his shot wide of the far post after being set up by Pereira - it might have been a different story. But Blackpool, who had beaten non-league clubs Eastbourne and Harrogate to reach the third round, took the lead against the run of play four minutes before half-time after a swift counter-attack ended with Jerry Yates tapping home Bez Kubala's low cross at the far post.

Albion showed more attacking urgency in the second half and Semi Ajayi - scorer of their goal in the unexpected draw at Anfield last month - equalised with a towering header from Kamil Grosicki's cross.

Gallagher should have put Albion ahead but lifted a good chance over the bar - and he was hooked soon after in one of five changes made by Allardyce.

Blackpool regained the lead after 65 minutes when they hit Albion on the break for a second time. This time Dan Kemp played the pass through, Yates helped the ball on for strike partner Madine to score with a fine first time shot into the bottom corner.

But Albion equalised for a second time when Krosicki's cross struck Olly Turton's outstretched arm and referee John Brooks pointed to the spot and Pereira converted the penalty.

Despite the disappointment Blackpool looked the better side in extra time. Yates had a close-range shot saved by Button, while substitute Sulley Kaikai fired over. At the other end Filip Krovinovic lifted a shot over the bar after being set up by Edwards.

Edwards was denied in the second period by a fine save from Maxwell and seconds later Ajayi was inches away from connecting with Pereira's clever chip before it went to the shootout.

Yates and Kaikai missed for Blackpool but Kenny Dougall, Jimmy Husband and Madine kept their nerve to secure the victory. Grosicki and Jake Livermore scored Albion's penalties, but the defeat underlined the task faced by Allardyce in preventing Albion from a quick return to the Championship.
