All of those Keepers would be out of our price range mate
It would either be spending money on an average to good UK based player or taking a gamble on a foreign keeper and hoping he comes good
We're not getting a Begovic/Lloris/Forster level guy without spending a decent chunk of change first, and I'm pretty certain Martinez would rather spend that money elsewhere
For that reason, we need someone who is an improvement on Howard at a reasonable price or we need to look abroad and hope we get it right
