After knocking out Manchester United in the last-eight of the F.A. Cup, Chelsea will be keen to continue their run when they face off against a dangerous Rubin Kazan side in the first leg of the Europa League quarterfinals.

The Blues are in a busy period at the moment, having already played two games in the last few days, and Rafa Benitez will have to keep an eye on his players' fitness before making a decision on the starting lineup against the Russian side.

"We are just concentrating on one game at a time," Benitez said. "I have to pick a team that can win a game, and just concentrate on this one -- the players have to be ready. We are doing really well so far.

"We proved against Manchester United that in a game against a team top of the table and the one that has won the most trophies in England that we can compete.

"When you play one game every two days you have to try it a different way but I am happy with what we are doing at the moment. It was an important game for us, we won it and we did really well against United and that means we have this level and we can do it.

"We are capable of competing and winning in every competition. The players have to be ready, mentally and physically, and they know how important it is to win every game, how important it is to win trophies and finish in the top three."

Rubin are far from pushovers, with the Russian side already knocking out defending champions Atletico Madrid and Levante in the previous rounds.

"I have very high hopes for this game," Rubin coach Kurban Berdyev said. "Rubin don't play such big teams every day and we can't wait for the game to happen.

"I have been to Chelsea before as a guest of Mr. Abramovich and I remember looking at the stadium hoping that one day I could bring my team here. This game will create history for Rubin -- and we've got used to not being favorites."

Chelsea do have a few worries, with Gary Cahill and Ashley Cole ruled out of the game through injury, while Demba Ba is ineligible having played for Newcastle earlier in the tournament.

Rubin will be without Alexander Ryazantsev and Yann M'Vila, while Alan Kasaev is a doubt.
