Frank Lampard believes Chelsea are beginning to bear the fruits from a summer of heavy investment in the transfer market after a 4-1 win over Sheffield United moved them up to third in the Premier League.

Despite a £220 million ($289 million) transfer splurge, the Blues did not hit the ground running as they won just two of their opening six league games of the season. However, they have now won four in a row in all competitions with three of the new signings, Ben Chilwell, Thiago Silva and Timo Werner on the scoresheet on Saturday, while another Hakim Ziyech won man-of--the-match for two assists.
