I only watched on TV - but can I just say in their (pseudo) defence...if we were that 'poor' then what did it make Utd? From what I saw (and maybe I was watching the wrong game...!), we totally outplayed Utd for the first half and for the first 15-20 minutes of the second. We just didn't score and they did.
The last 20 minutes seemed poor - it just seemed that by then they had given up on the idea that they could score.
