So he should be back by the end of the month.
I feel sorry for him, because he's a great lad, and a really good player. However, he has two problems - the obvious injury issues, and the fact that he always seems to take a while to get back up to speed after a period out. Sturridge, for example, would come back from injury and immediately make an impact. He's lost a bit of that pace (or the willingness to use it) over the last few years, but you know that if you put him on the pitch he will contribute. Meanwhile, Lallana needs a good run of games (I'm talking months) until he's back playing near the level he's capable of. I suppose it's just the kind of player he is - he needs that sharpness. This coupled with his injury frequency are a pretty bad mix, and I think he will be a luxury player for us from now on.
I'm raring to see the Lallana of 16/17, I miss that player a lot.
