I knew man utd were going to lose to west brom thierry henry

I think there may be a few issues with your statement!

Firstly, Thierry Henry is a former professional footballer who played for Arsenal, not Manchester United. He's a legendary striker who won numerous titles with Arsenal, but he's not associated with Manchester United.

Secondly, Manchester United did not lose to West Bromwich Albion (West Brom) in a specific match that you're referring to. Manchester United and West Brom have played each other many times in the Premier League, but I'm not aware of a specific match where Manchester United lost to West Brom.

If you're thinking of a different match or a different team, please feel free to provide more context or details, and I'll do my best to help!
