Chelsea fans were treated to an extraordinary comeback in the second half against Ajax. Frank Lampard's men looked dead and buried to the untrained eye. However, the English boss insisted he told the players at half-time that they would rescue a draw. "I said to the lads at half-time – I’m not trying to say how clever I am – but I said, 'I think we’re going to draw this at least 3-3, could be 4-4, could be 4-3 and we could win it. It’s up to us,'" he said on BT Sport. That's exactly what they did, coming from 4-1 down to make it 4-4 thanks to three goals in 11 second-half minutes from Cesar Azpilicueta, Jorginho (penalty) and Reece James. Kurt Zouma goes on ridiculous run v Ajax

Chelsea's incredible comeback vs AjaxThe 19-year-old became the youngest player in the club's history to score in the Champions League. However, many Chelsea fans will have missed that last 45 minutes of utter madness, which also saw a potential winner disallowed and both Joel Veltman and Daley Blind sent off. With their side trailing so heavily, scores of supporters made for the Stamford Bridge exits to get an early train. Perhaps it was the deafening noice that began to ring around the stadium, but suddenly something must have clicked - for there are several reports of them trying to get back in once they realised what was happening. 

In the BT Sport studio, Gary Lineker had little time for Chelsea fans who gave up on their team. 

"We saw fans walking out at 4-1 and they must have said 'what did I do? Why did I leave?' when they got home," he said. 

"It just shows you with football you never know. You never give up."

Rio Ferdinand added: 

"You can't walk out. The spirit within this stadium and this club the way they have responded to Frank then you can't come out of this stadium even at 4-1 down."

It's testament to the never-say-die attitude that Lampard has brought back to west London - but it's an indictment of these Chelsea fans all the same.
