Honestly, the more I think it through the more sense it makes, I think it'd help at both ends of the pitch.
Demiral fits the mould of a typical Leicester signing in being young, playing senior international football and coming with a good reputation, but importantly it'd give us flexiblity in being able to apply 3-5-2 more regularly with three top class CBs. We'd be able to get better attacking width from Chilwell & more crucially Ricardo if we didn't fancy the Barnes/Perez combination which in all honestly hasn't been prolific, though not a disaster either. If we can't secure a top class winger in this window (which will be difficult) then this might be the best idea for Rodgers.
I'm not sure how it would affect Vardy by playing two up top frequently, but ultimately it at least gives us a different option and we can play Perez & Iheanacho in their more natural positions. The main plus here though is that we'd have the chance to rotate between Soyuncu/Evans/Demiral even if we continue to play with two CBs, and we'd not rely on the ageing Morgan as third choice (who is likely to leave us in the summer) and Benkovic can go on loan to a Championship club to get some much needed first team football.
Demiral is keeping De Ligt out of the Juve team at present but he's Juve's second highest earner behind Ronaldo, so transfer fee aside Sarri is under massive pressure to get the best out of him alongside Chiellini (with Bonucci third choice). I think Sarri actually said he was being rested as he's played a lot of football over the last calendar year. I think Juve want around €40m for us to form the potential Turkish Wall so I assume that's why we initially offered a loan with an option to buy, but let's see what happens. I'd rather go with quality at a higher price than an average back up who'll still cost £15m+. Competition for places is a good thing, which you can't say we have right now at CB.
