To be fair to IEC, there hasn't been any announcement of what our transfer budget is. I'm not saying I think we're sitting on a £50 million war chest or anything, but until the window is over, we fans won't know what we had to spend.
It's safe to say that they're not chucking a fortune at us, but since this is their first proper transfer window, they may have made some money available (over and above what we'd already have had).
As a club, we're not renowned for our great communication where transfer policy, budget and targets are concerned, so it's possible that they've made some money available and we just don't know about it (yet?).
It's also entirely possible you're 100% right and they haven't given us a penny other than what we have got from outgoing transfers, but at the moment, there's simply no way of knowing.
