David Moyes says he is "really excited" to not know the true potential of his West Ham team after they opened their Europa League campaign with a Group H win at Dinamo Zagreb.
Michail Antonio and Declan Rice both scored as the Hammers announced themselves in the competition with a dominant performance against the Croatian champions.
It ensured that Moyes' side continued their unbeaten start to the campaign, and barring qualifying games, delivered a first victory in Europe since 1999.
"Zagreb have a really good history in European football so I knew it was going to be a tough game and the players were made aware of that," Moyes said.
