THOMAS Frank hailed an ‘unbelievable’ performance by his Brentford players as they booked a place in the Championship play-off final for a second consecutive season but warned it will count for little if they don’t get the job done at Wembley.

Marcus Forss’ 81st-minute strike sealed the Bees’ progress against a 10-man Bournemouth side who had gone 2-0 up on aggregate when Arnaut Danjuma capitalised on some lax home defending to open the scoring inside five minutes.

Ivan Toney equalised from the spot and the hosts’ chances received a boost on 28 minutes when Chris Mepham was sent off for hauling down Bryan Mbuemo.

Vitaly Janelt’s speculative effort from distance looped into the top corner five minutes into the second period to level the tie on aggregate before Forss diverted Emiliano Marcondes’ cross home to spark jubilant scenes inside the Community Stadium.

“What a rollercoaster of emotions,” Frank said. “Only sport, and especially football, can do that.

“I smashed my foot into the ice cooler after their goal, then I thought I’d better keep my head, and then 10 seconds later I smashed my foot into the bin next to it.

“At 2-0 behind it was tough – but I was not in doubt that we could still get there.

“It was a crazy goal to concede but we talk a lot about winning the next moment and the players were unbelievable in their mentality and attitude to keep going. Two key incidents [the penalty and red card] went our way but they were absolutely correct.

“I just had a feeling, the way we performed out there, that it would come. Marcus [Forrs]’ goal is one of those moments he will never forget.

“We have achieved something big but we know the ultimate is to win on Saturday. There is a long, long way before we are across the line.”

Brentford will take on Swansea in the final hoping to go one better than last season’s showpiece, which saw Frank’s side beaten 2-1 after extra-time by local rivals Fulham.

Unlike last year, there will be a crowd inside Wembley – though fewer than 4,000 fans will be present from each team with the capacity limited to 10,000.

The charismatic Frank whipped the supporters inside the Community Stadium on Saturday into a frenzy pre-match, sprinting around the side of the pitch, and hailed the impact of the fans in helping his side over the line.

“We knew our fans would be a factor,” he said. “I’d never do that, it’s not what I really want to do, but I went a little bit out of my comfort zone because these games are always about the finest of margins.

“The message to the players was we need a top performance from them, and we also needed a top performance from the fans, and we got that.

"Four thousand fans felt like 20,000 and had it been a full stadium, they would've raised the roof."
