Can understand the reasoning but big strikers who play for teams that can hurt us are few and far between.
The key thing is are we looking for a starter or a back-up? If a back-up, he is a good option. Top class players are not happy to be third or fourth choice. If we are looking for a first choice, then he is not a particularly good signing, IMO. This is why I am not sure we are interested. We have gone from looking for a first choice in Maguire to now searching for a back-up?
If we signed him as back-up, he would be useful as he is left footed (if my memory served me correctly), homegrown (I believe) and he is good with the ball. The fact that he is left footed gives us options as Laporte is our only left footed centre half. A further positive is that he is less likely to get in the way of Garcia's development path.
Like you, I do like the idea of having a centre half whose head is a magnet to the ball. Vinny's ability to win almost all headers when teams were 'throwing it in the mixer' was so important to us down the years.
