Krychowiak was subbed off in the first half of Wednesday's match against Manchester City with a suspected injury. He was replaced by Gareth Barry.
Analysis:
The specifics of Krychowiak's injury were unclear, as he was able to walk off the pitch on his own, though he went straight down the tunnel to the dressing room. He did get his leg stepped on by Fernandinho, but Krychowiak didn't appear to be limping at all as he left.
