Buying a new defender

[PeterParker]

Is it a must for the transfer window?

Things with Vinnie are bad, as we all saw it. Call it bad luck, call it anyhow, are we ready to give him more time?
I hoped that Tosin would step up after what we saw this summer, but looks like he is not a choice for Guardiola (maybe that contract issues might be why).

So, should we go for another one? The prices will go up for anyone we will show interest in.
