Ahead of tonight's meeting, the Scot said: "He has left a big hole, not only on the pitch but in the changing room, because he is a fantastic character - you miss people like that, especially in games where you have to dig in.
"Ours is a bit shabby in comparison, it seems - they have fingerprint entry to their place - but that's what an unlimited budget does for you."
Back in his old surroundings, Sidwell will be made to feel at home.
"He will get a good reception, because everyone saw how he put himself on the line for us last season even when there was talk of him leaving," Murty predicted.
"He never shirked a tackle and he never stinted in his spadework in the trenches for us. He is a top lad, and we wish him all the best - starting after this game."
