It tells us where he is in his recovery and moving out onto the pitches is huge. Grass is an unstable surface.It's good news but that tells us something which we didn't know? I mean, does it imply he will come back earlier than planned? I'm not sure.
Good news though. We are missing him a lot. He will need a month to hit form, so hopefully he will be back to his best for the 2nd leg in the last 16 in the CL.
Players can say they hope to be back by Jan/Feb but I always prefer to see evidence rather than words.
