Fabio Carvalho struck in injury-time to earn Brentford the point.
"It’s disappointing not to win," the fullback explained. "We came here to win and we found ourselves a goal down, and we adapted the way we played and got ourselves back into the game. They are a strong team, and they punished us.
"We’re not happy with drawing, but we’ll keep fighting. We’ll have to accept the result and move forward."
James also said: "There are many factors as to why the first half wasn’t good enough. It’s a difficult place to come and we’re coming into games after an international break and that’s always tough. It’s no excuse – we have super high standards here.
"They caught us on the counter (in the first half), and we were prepared for that, but we didn’t deal with it. The second one is a set-piece where they are super strong and we didn’t deal with it today."
