Alex is ready to make his Premiership return for Chelsea.
The Brazil defender is yet to taste Premiership action this season, but is now fully fit.
Alex told chelseafc.com: "I am feeling good and I am very happy with my fitness,' reports Alex, now totally over the groin surgery that kept him out of the start of the season.
"The last 20 minutes in Madrid I was very tired but I was so happy that I come back to play and I think in my opinion that I played good. We drew 2-2 but it was okay, a good result. [Sergio] Aguero was difficult and his second goal, the free-kick, was a very good goal.
"I don't know if I will play but I hope to help the team on Saturday, or the next games after that."
