West Ham boss David Moyes admits they know little about Europa Conference League opponents FCSB.
Moyes says it's too soon to consider winning the competition.
"I think it's difficult to assess at the moment. We'll have the same situation as last year, when the teams drop down from the Europa League. I'm not earmarking any particular games as the most important. We want to try and win all of them. We start tomorrow night and we're looking forward to it. We've got a group with some history in it," he said.
He added that they have recognised "one or two players we need to deal with" in the Hammers' opponents, FCSB, who finished second in the Romanian Liga I last season.
"We've watched a lot of games and tried to get to know the players as best as we can. We're getting a better understanding of FCSB," he said.
In terms of team news, Moyes says Gianluca Scamacca is "getting closer to fitness" and has just started back at training.
