Keeping the same back 4 for the sake of it makes no sense, if Taylor is left back then I can see Sturridge having a field day against him. Stick Santon in and then Chelsea have to try something different because I'm sure they will target Taylor as being a weakness.
I'd rather have Santon in for Taylor, but I wouldn't play Taylor left wing.
My ideal choice would be HBA with Best returning, then Sammy if not.
