Brighton's signing that Italian Coppello looks good business.
And that winger who's now played for three team's look's useful,but he won't finish the game the amount they're using him.
Doesn't it actually transfer the problem outside via the exhaust of heat? Which is the the product of what you're trying to achieve let alone the energy required to run it?
I say this as someone who has benefited from it on many occasions at work!
