The issue is not that Maguire is immobile, but that he is extremely immobile. All players have weaknesses, but when they are as prominent as Maguire's lack of mobility they impact not just the other CB and how he plays, but our overall defensive setup.
Another example is Juan Mata's lack of physicality, which makes him pretty much useless when we are not in possession and is similar to us defending with one less player.
We played floating corners earlier in the season to give Maguire time to get to the ball. Leicester and Maddison played hard and accurate topspin corners with Maguire running in anticipation of where the ball would most likely end up.
But to me so was Blind & I know Blind is a hard player to talk to on redcafe as some people rate the player and some do not -
But the guy had weaknesses.
He played to overcome his weaknesses, sitting back, reading the game or doing the complete opposite - reading the game early to the point that he would read the game before anyone else and be the first to initiate the defensive action whilst Smalling sits back. Smalling was physical and was much more a reactive defender whilst Blind was a proactive defender - one was physical whilst one was technical and much more mentally gifted on his first 5 months as a CB.
Now even if you don't rate Blind as a CB,
Tell me - how do you think that Blind would have done next to Lindelof? Where Blind was a proactive defender and Lindelof would have to get the position right for the reactions of the attack - the type of attack that I usually see him scared to defend against?
I don't think they would do well.
For me, Maguire plays too much like Blind to play next to someone like Lindelof - he isn't a reactive defender and he is more a proactive defender. He wants to be the first to tackle in the partnership (we see this with Lindelof - he goes across Lindelof, across CDM, across Shaw to initiate a tackle), he wants to bring the ball out to try and find a pass or atleast release pressure from our back line. What we need next to him is a reactive defender - a physical defender that heads the ball, that players struggle to get past if they manage to get through, that's main goal is to recycle possession and pass it back to Maguire or Blind to initiate an attack once again.
Its why I said at the start of the season, 2 ball playing defenders is one of the most overrated tactics in the history of football - puyol & pique, Ferdinand & Vidic, Terry & Carvalho etc - the back line even whilst pressed is never that pressurised for it to require 2 ball playing CB's - because usually when if you play that, you lose an element of defensive stability. The best teams never really had 2 ball playing CB's, they had one.
We need to stop the Lindelof & Maguire thing - get Maguire a proper defensive partner for Maguire to be our ball playing proactive defender.
