Rosenior's side went into tonight's game knowing we needed to overhaul a three-goal deficit after our 5-2 defeat in Paris during the first leg.

Early strikes from Khvicha Kvaratskhelia and Bradley Barcola inside the opening 15 minutes made that task even harder, and Senny Mayulu made it 3-0 on the night - and 8-2 on aggregate - with a third just after the hour mark.

Our head coach admitted the two early PSG goals ‘knocked the wind out of our sails’ and meant there was little opportunity for the Blues to mount a fightback in the tie.

‘We obviously wanted to put up more of a fight than what we did,’ Rosenior explained. 'Credit to PSG. Their possession play was really, really top in the game and over the two legs, they deserve to go through.'

Rosenior continued: 'I think football is about flow and momentum, and if you give the opposition flow and momentum without them having to work so hard, they get more confident.

'So, if I look back – and I've already watched some of the game back – the first six minutes, we're in the game, we're in their half of the pitch and then they score.

'I know Mamadou (Sarr) is a great young player, and this is something you have to ride and learn from, but we make a mistake, an individual error. There's nothing tactical and Kvaratskhelia, because he's a top player, scores.

'That gives them confidence, gives them a cushion and Barcola hits one from 25 yards into the top corner. I don't remember them having a shot either side of that.

'We have to learn at the top, top level to be clinical and to make sure we keep the back door shut. We've done neither over the two legs, that's why we're out of the competition.'

As the tie drifted away from the Blues, Rosenior opted to make a triple change just after the hour mark, which saw Enzo Fernandez, Cole Palmer and Joao Pedro replaced by Romeo Lavia, Alejandro Garnacho and Liam Delap.

Rosenior admits that, as a coach, 'you never want to take off your best players' but says it's important to continue carefully managing his players after an intense 18 months.

'It's a reality of where the group are,' he said. 'They've played over 100 games in 18 months. They've had no break in terms of the international games and then there's the travelling that, say, Joao Pedro, Enzo Fernandez or Moises Caicedo do to South America.

'It's not an excuse, it is a by-product of the success of the Club World Cup and it's a great thing that the club achieved at the Club World Cup.

'But you're seeing with Reece (James), you're seeing with players, that if I don't manage their minutes, their likelihood of getting injured is increased very highly.

'I want us to make sure we're in this competition next season as a minimum. We're still fighting for an FA Cup, but I have to make maybe really difficult decisions that at the time probably don't look great, to be honest.

'You never want to take off your best players when you're five goals down in a tie, but I want to make the right decisions for the football club in the long term as well.'

Rosenior also stated that he wanted to thank the Chelsea supporters, who had whipped up a fervent atmosphere inside Stamford Bridge in the early stages of the contest.

'We want to make sure we don’t go through many more nights like this,' said Rosenior. 'This is a fantastic football club where the fans want success instantly – that's rightfully so for the size of the club.

'I have to say, I understand because of the aggregate scoreline in the tie, why fans are frustrated. They want us to win; I completely get it and I understood that before I came in. I also want to make them happy and give them the nights they deserve. Not just me, but us as a group, as a team.

'That was a really, really difficult one to take because of the manner in which we went out this evening.'
