Manchester City manager Roberto Mancini hopes to see Sergio Aguero and Vincent Kompany back from injury for the match against Newcastle on March 30.
But Mancini admitted Kompany's injury as been a 'big problem' for the defending Premier League champions. The Manchester City captain has been out for over a month after suffering a calf problem in the FA Cup fourth round against Stoke.
Aguero picked up a knee problem in training before City's 1-0 victory over Aston Villa in the Premier League earlier this month.
His last match for Mancini's side was during the 2-0 home win over Chelsea in February. But Aguero's recovery is progressing well, and Mancini is confident he'll be ready to play a part in City's run-in as they look to chase down league leaders Manchester United.
Mancini said: "Sergio is in Argentina but he will come back on Sunday. Vincent is not in our plans for tomorrow. But I think he will be ready for the Newcastle game, like Sergio.
"It is difficult. Vinny is a really important player for us and now it is 45 days he has been out. It is a big problem."
Manchester City face Everton in the Premier League on Saturday, as they look to close the 12-point gap to their table-topping city rivals.
Mancini's side overhauled United last season to win their first ever Premier League title, overturning an eight-point deficit at one stage.
Carlos Tevez has picked up the slack in Aguero's absence, scoring a hat-trick against Barnsley in the FA Cup fifth round, and the match-winning goal against Aston Villa.
