I think people underestimate Smalling
And yes, while not great, Maguire is better than what we currently have. With a world record fee for a defender we are not buying a world class center back, are we?
Smalling has been at the club since 2010. His best season was under LVG and lasted for that one season. If you can't cement yourself as a core CB in a decade, there is no "underestimating". He's been estimated and he's just average. We have no idea what maguire could be. He could take a step up, he could be a complete flop. I'm not going to base his entire career off how he is managed at Leicester. If Ole or the transfer board only have a few select targets and he's in the top few, then we have to try and get him. If we can't do a deal, we'll likely walk and keep the ones we've got.
This idea being pushed by others on this thread that we just "buy X because i think he's good and cheaper" is just fan speak. The club have targets, we are fans. We have no say on the club.
