The Hammers lost 2-0, and Roger admits:
"We conceded two soft goals, but when we were 1-0 down we had the chance to level through Nigel Pierre when he was clean through with the goalkeeper, but he shot wide.
"Omer Riza had a great chance to level as well, but shot straight at the goalkeeper and, from the corner, he headed wide.
"Then we conceded a second when David Forde came from a cross he didn't get, but even then we had a chance to pull one back with a penalty.
"Omer Riza was pulled down, Grant McCann took the penalty, but the keeper guessed correctly."
Trinidad and Tobago international Nigel Pierre, who plays for Joe Public in his native country, was on trial but fellow countryman Brent Rasheen, currently with Levski Sofia, did not receive international clearance in time.
"Nigel tried hard," says Roger, "but without a lot of success - I would not say he played badly."
Although the defeat was disappointing, Roger adds:
"Apart from the two goals I can't remember David having a real save to make - but that game was very unlike how we have been playing all season."
On the plus side, he says:
"Anton Ferdinand made his reserve team debut and he did quite well."
Ysrael Zuniga scored both Coventry goals.
