Does David Moyes really need a war-chest of, say, £50m. Tbh, I think not.
Where we are currently positioned speaks volumes. Constantly on the coat-tails of the top 4, and of course, in a semi-final with the best 3 in England.
David Moyes does need new additions, there's no question about that -- no matter how good you are, you always have to strive for better.
Big money helps, of course it does, but, it has to be spent wisely. A manager may be in a position to spend £50m, what though, if it's spent on four players and for whatever reason (just like Jo at Man.City) the new players don't fit-in.
The together-mentality David Moyes has indoctrinated into his squad can't be bought with money. Subsequently, of course money does help but it is not everything -- just ask Mark Hughes at Manchester City -- arguably, his best player is a home grown talent (firstly at Cobh Ramblers) -- Stephen Ireland.
