My thinking was that possesion and calm away at OT is important so thats why I was thinking Allen's boringly simple passing might just help to ease us in. Despite Lucas' form not being amazing, I dont think it is a suprise that Gerrard has started scoring more goals and generally played better since his return to the side. I like Jonjo and could see a strong case for him playing, he would blast past Carrick, Scholes etc.
Personally, I thought Sturridge looked dangerous but unfit which is perfectly acceptable considering how long he has been injured, I think him being a supersub makes most sense. You certainly wouldnt want to be 1 or 2 nil down and take him off to bring Downing or Suso on to chase the match. I think Jonjo would make for a strong impact sub against tired old legs at United, maybe bring them on as a pair with 20-30 mins to go.
