How do you know his value will increase in 3 years. How much is Fofana worth today in comparison to the 75m we paid. How do you also know that Guirassy will be worth nothing in 3 years.
At some point there has to be some focus on the here and now. You cannot continually buy players who are going to be great, possibly, hopefully in 3 or 4 years time. Virtually every pundit involved in football made the comment last year that our football, even in the bad times, wasn't bad. We just couldn't score goals. So we decide to not go for a proven quality striker to lead the line and end up going for a second string Villa striker that there manager is perfectly happy to let go (with no second striker currently in place btw)
