A quickfire exchange of headers late in the first half saw West Ham United held to a battling 1-1 draw by Everton at London Stadium.
The Irons poured forwards in the first period and forced Everton keeper Jordan Pickford into some excellent saves, before Issa Diop's glancing header from Robert Snodgrass' free-kick granted them a well-deserved lead shortly before half-time.
The old adage that a team is never more vulnerable than in the moments after they have scored came to the fore, however, when Everton left-back Lucas Digne's corner was flicked on at the near post by Mason Holgate and converted by Dominic Calvert-Lewin just three minutes later.
Despite making plenty of running in the second half, both teams struggled to create anything like the opportunities of the first period, and eventually had to settle for a hard-fought draw at London Stadium.
