In my opinion I don't want us going out spending a ton of money again in the Summer, why can't we use our scouts and get some talent in from South America like Zuculini?
Dortmund have had successul results using a good scouting system, so why can't we? You don't need to spend fortunes.
I know we need a center back, but is spending 40m on Mangala for example worth it? He looks individually brilliant, but will him in a partnership with Vinny be brilliant?
I think we need a left center back, a back up midfielder and another attacking midfielder, but a big emphasis should be on Pellegrini coaching the best out of what we have in the Summer, at least by then they will all have had a season to get used to his tactics etc...
