Arsenal have been handed a major boost with the news that goalkeeper Wojciech Szczensy and defender Johan Djourou have returned to training.
Szczesny has been out since dislocating his finger in the Champions League last-16 clash at Barcelona a month ago, but could return for Sunday's clash against Liverpool, meaning Jens Lehmann would drop to the bench unless Manuel Almunia recovers from his knee injury.
Djourou had been out with a dislocated shoulder, but he too returned to training this week and could feature.
Manchester City's hopes of reaching the FA Cup final and reaching the Champions League took a knock with the news that Carlos Tevez has been ruled out for a month with a hamstring injury, while Ryan Nelsen will miss the rest of Blackburn's relegation battle with a knee problem.
