Roy Hodgson is confident Javier Mascherano will be fit for Monday's clash at Manchester City- but is less certain about Daniel Agger's participation at Eastlands.
The duo did not feature in the 1-0 Europa League success over Trabzonspor but the boss is hopeful they could both be involved against Roberto Mancini's men.
"I've got great faith Javier Mascherano will be fit to play the game on Monday," he told his post-Trabzonspor press conference.
"He took part in a training session today and has made a quicker recovery than we could have even hoped for. There's still four more days, so I would be very disappointed if he is unable to play.
"Daniel Agger is very positive and tells me he will be okay to play but I must take some medical advice on that because I wouldn't want to put his health at risk. Concussion is a very serious injury - I may have to listen to the doctors as well as Daniel.
"If it's up to Daniel, he's telling me already, to count him in on Monday."
