Manchester City are facing defensive concerns ahead of their clash with [Albion](https://www.theargus.co.uk/sport/albion/?ref=au).
Josko Gvardiol and Roben Dias both went off injured during the 1-1 draw with Chelsea.
Gvardiol had to be helped off after an awkward collision on the halfway line early in the second half.
Dias left the action going into the final stages.
Asked initially about Gvardiol after the game, City boss Pep Guardiola said: “We will see tomorrow, but It doesn’t look good for him or Ruben.”
He added it “looks like” Dias had suffered a muscle problem.
Guardiola said: “I didn’t speak with the doctor but, if Ruben is out, it is because he felt something
“Of course we have a lot (of injuries). John Stones is missing for many months. Ruben will be out and Josko will be out.
“Always we know with Nathan (Ake) that he cannot play regularly.
“After what happened last season, if we stay strong we will find a solution and the spirit will be there.
“If the spirit is there, we will be there.”
City go into the midweek round with a six-point deficit to make up on leaders Arsenal after conceding a late equaliser to Chelsea.
Despite the dropped points, Guardiola was pleased with his side’s performance, adding: “They didn’t create much.
“We were extraordinary in all departments except we could not score a second or a third or a fourth.”
