The Catalans have spent heavily across the pitch so far in the summer window, and their coach wants to see the new signings make the difference
Ernesto Valverde is expecting a swift impact from €224 million (£202m/$251m) trio Antoine Griezmann, Frenkie de Jong and Neto at Barcelona.
France star Griezmann became the Liga champions' third major signing of the close-season last Friday, after Barca paid his €120m release clause at Atletico Madrid.
De Jong had agreed to a move to Camp Nou in January for an initial fee of €75m, having been courted by a number of Europe's top sides due to some standout displays for Champions League semi-finalists Ajax.
