Pretty much. This happens all the time. Half decent players are defended because we focus on the 25% of games that they're good in and ignore the rest.
I still think we'd be better off replacing him.
We always fail to capitalise on it by selling as well. I have no problem with Maguire personally or whatnot and I’m fine with him as squad depth.
However, another CB should be on the shopping list and if that means less opportunity for Maguire and someone makes a good offer then he can go.
Frankly, I’m not opposed to Varane moving on as well. He’s an excellent player but we need a proper partnership to build at the back. We all remember Bruce and Pallister, Stam & Johnsen, Ferdinand and Vidic.
Martinez seems like one half of the puzzle if he can get fit and return to form but a strong, quick and physically dominant centre back needs to be on the list.
