Chelsea FC head coach Liam Rosenior is expected to field his strongest available line-up in the Champions League round-of-16 first-leg match against Paris Saint-Germain on Wednesday. The Blues boss took some risks by making nine changes in his team in the FA Cup fifth-round win over Wrexham on Saturday. Chelsea needed extra time to secure the win in the end, but they should reap some rewards with several key players getting plenty of rest ahead of the trip to France. Robert Sanchez reclaimed his spot in goal at the weekend, but it remains unclear whether he will get the nod to start over Filip Jorgensen against PSG. In defence, Chelsea have relied a lot on the centre-back partnership between Trevoh Chalobah and Wesley Fofana, and this is unlikely to change in such a big game. Reece James and Marc Cucurella, on the other hand, should be the starting right-back and left-back, respectively. In central midfield, Andrey Santos and Moises Caicedo are expected to start, while Enzo Fernandez will likely continue to play in a more advanced attacking role on the left. Cole Palmer is expected to start as a roaming number 10 as usual, while Pedro Neto likely starts on the right wing. The Portugal international played 100 minutes against Wrexham at the weekend, but the alternative, Alejandro Garnacho, played the whole 120 minutes. In-form Joao Pedro should obviously start up front. There is a possibility that Rosenior could opt for a back-three system, but Chelsea have not had much success with the structure recently. Chelsea even tried it in the first 65 minutes against Wrexham, albeit with many key players rotated out, and conceded early. Rather than taking risks with a back-three formation, Chelsea are expected to stick with a back-four, with Fernandez playing a hybrid midfield role to try to dominate possession. The predicted Chelsea line-up vs PSG is expected to be a 4-2-3-1 formation, with Jorgensen in goal, James and Cucurella as the full-backs, and Fofana and Chalobah as the centre-backs. Santos and Caicedo will likely start in central midfield, with Palmer and Neto on the wings, and Pedro up front. Fernandez will play in a more advanced role, and his performance will be crucial to Chelsea's success. The match against PSG will be a tough test for Chelsea, but with their strongest line-up, they have a good chance of getting a positive result. Rosenior's team selection will be crucial, and the goalkeeper decision will be closely watched. The match is scheduled to take place on Wednesday, and Chelsea will be looking to get a good result ahead of the second leg. The Champions League is a top priority for Chelsea, and they will be giving it their all to progress to the next round. With a strong line-up and a good game plan, Chelsea can get a positive result against PSG and take a step closer to achieving their goal.
