Roberto De Zerbi appeared to be both shocked and concerned when he learned of West Ham's 2-0 win against Arsenal during a press conference on Thursday evening.
David Moyes' side have now claimed back-to-back 2-0 victories against both Manchester United and the Gunners, with the Hammers now set to face off against Brighton on Tuesday night.
While De Zerbi's men claimed a big 4-2 victory against Tottenham on Thursday, with Pervis Estupinan scoring a sensational goal from outside of the penalty area, the Brighton boss looked worried upon hearing about the result at the Emirates during his post-match press conference.
