Chelsea take on Paris Saint-Germain in the Champions League last 16 with the first leg taking place in the French capital on Wednesday evening

As far as challenges go, there are not many bigger than trying to beat the reigning European champions over two legs. For Chelsea, that is the task ahead of them, with two matches on the horizon against Paris Saint-Germain, who are looking to defend their Champions League crown.

The Blues, though, will take confidence in the fact they humiliated PSG less than eight months ago. The two squared off in the final of the Club World Cup in July, with Chelsea scoring three first-half goals in New Jersey and that was enough to embarrass the French side.

Plenty has changed since that afternoon at the MetLife Stadium. Liam Rosenior is now the man in charge of the world champions and he is looking to lead his side to European glory, though against Luis Enrique, the Chelsea head coach will have his work cut out.

Wednesday evening sees the two lock horns at Parc des Princes in the first leg of the last 16 tie. Both sides have suspension concerns going into the match, with the return leg at Stamford Bridge on March 17.

Champions League rules say that any player who picks up three yellow cards - or any subsequent odd number of bookings - from the league phase onwards will be suspended for the next match. The bookings only get wiped after the completion of the quarter-finals.

For Chelsea, Enzo Fernandez and Andrey Santos are both on two yellow cards. As for PSG, left-back Nuno Mendes is one booking away from a one-match suspension.

It will be a huge blow for Rosenior if he was to lose either central midfielder but he has just welcomed back Romeo Lavia and Dario Essugo. The duo, who play in similar positions to Fernandez and Santos, both featured during Chelsea's dramatic FA Cup victory away at Wrexham on Saturday evening.
