West Ham United suffered a 1-0 defeat to newly-promoted Nottingham Forest in their first away game of the Premier League season.
In a hectic clash, Forest got their winning goal through Taiwo Awoniyi on the stroke of half-time just minutes after Said Benrahma had a goal disallowed by VAR.
VAR was in action twice more in the second half as Brennan Johnson had a chip disallowed by VAR for offside before the Hammers were awarded a penalty for handball, with Declan Rice's effort saved by Dean Henderson.
