Julen Lopetegui is yet to set the world alight since taking charge of West Ham over the summer, despite spending over £100m in transfer fees.
West Ham have won just one of their six games in the league under the Spaniard but their performance against Brentford suggests improvements are being made.
The Hammers fell behind inside a minute and then enjoyed the majority of possession and chances for the remainder of the first half.
Lopetegui made two tactical changes at half-time, brining on Konstantinos Mavropanos and Carlos Soler for Mohammed Kudus and Emerson.
West Ham looked much-better balanced in the second period and it took just under 10 minutes to get level.
