Shields, Paton, McGuire, Miller and Wilson will be in no way replacements for the OOC players. We're a fortnight into the transfer window that doesn't close till September. Think back to the January window where all our buissnes was done on the 31st of Jan/ 1st+2nd of Feb or back to last summer where almost all our incomings came within the last 3/4 week. That's without the worry of trying to get buissnes done early due to not being in Europe this season. Not even close to being at the point of needing to worry yet.
