Rovers boss Sean O'Driscoll says that he was pleased with his team's performance - despite Kevin Nolan's goal winning West Ham all three points.
Nolan struck after just five minutes to score his first competitive goal for the club - and secure Sam Allardyce's side their first win of the new Championship campaign. However Rovers boss O'Driscoll remains pleased with his side's contribution - especially so after the half time break when they threatened to steal a point."I'm probably more disappointed with the players reaction to things in the first half," he told doncasterroversfc.co.uk. "We know we're going to come up against good teams in this division and we have a team like West Ham, who we know are going to be strong. It's not always going to be perfect for us so when we get disappointments we need to react a bit better.
"We said second half that we're not going to tick all the boxes every time, but if things don't go well we need to make sure we do the basics right.
"We need to get into the right shape for goal kicks, keep the right shape all the time when the ball's dead, that doesn't matter if you've got injuries or less resources than anybody else, all we're asking them to do is everybody can do - you've just got to value it more.
"The goal came from a poor pass. We committed a similar sin against Tranmere and didn't get punished , but we're up against sides in this division that will punish you if you give the ball away in a sloppy manner."
