Manchester City midfielder Fernandinho could be fit to face Barcelona in the Champions League this week.
The Brazilian has been out for the past fortnight with a muscle strain but has trained ahead of the first leg of the last-16 tie at the Etihad Stadium.
Manager Manuel Pellegrini said: "He has a chance. He is in the squad list for tomorrow.
"We will see tomorrow who can start but he has worked without any problem."
Fernandinho's availability gives City a big lift for what will be one of the biggest nights in the club's history.
As expected, however, top scorer Sergio Aguero will not be involved, having failed to overcome a hamstring injury in time.
Pellegrini, speaking at his pre-match press conference, said: "He is not in the squad list.
"We will see if he can be fit on Saturday, but maybe that is also difficult."
Defender Matija Nastasic is also unlikely to feature, having not played an active part in the open training session at Eastlands.
