Chelsea against Paris Saint-Germain. The reigning world champions versus the current European champions. It is the kind of match-up the UEFA Champions League was made for. Two previous winners of the continent’s biggest competition going head-to-head across two legs in Paris and London.

The first of those games takes place in France this evening, with kick-off at 8pm UK time, and Rosenior is eager to get going.

‘For sure, how you gain experience is by living through different experiences,’ he said in his pre-match press conference at the Parc des Princes.

‘I can’t wait for the game because it’s going to be two outstanding young teams who play with their own identity and their own style.’

The Blues take on the current Champions League holders tonight and Rosenior knows all about the quality that Paris Saint-Germain possess. He faced them three times during his time in France with Strasbourg, returning across the Channel with honours even after recording one win, one draw and one loss in his three games against Luis Enrique’s side.

With that first-hand experience, he isn’t paying too much attention to the talk about whether the Parisians’ dominance may be slipping after a Ligue 1 defeat to Monaco in their last game, which means their lead at the top of the table is currently just one point.

‘PSG were so good last year,’ continued Rosenior. ‘Obviously, I was working in France last year and witnessed their journey to win the Champions League – I was admiring it.

‘When you have success, people want to knock you down. That’s normal, a part of life. I’m sensing that here at Chelsea as well. When you are a top-level club, when things aren’t going so well, people will speak about it more.

‘I won’t speak about the difference between now and then, but in terms of the quality of their team and the opposition manager, they are world-class.'

Of course, opponents of such quality are to be expected when you reach the knockout stages of the Champions League. For Rosenior the task is simple, make sure his players are up for the challenge and return to London with a result which will allow us to finish the job in next week’s second leg at Stamford Bridge.

‘It would be crazy to now expect anything else,’ he added. ‘I expect a very difficult challenge, tactically, physically, technically. They have world-class players but we do too. So it’s going to be a great game for the neutral.

‘We have to remember it’s a two-legged game and make sure we have discipline and focus in terms of that aspect. But I think in terms of a fixture, it will be an exciting game for the neutral.’
