Any player with the relevant Premier League experience is going to coast absolutely stupid money to buy.
What doesn't help is that any player we seem to sign doesn't get the chance to prove themselves by playing games!
Your final sentence is the only important one, none of us will ever know how good, (or otherwise), these new signings are, until/unless they are given a proper run in the tam. How can anyone say Andone, Balogun etc. show the most promise when they have barely even kicked a ball for the first team?
