We played like champions tonight - Man Utd's Ferguson
The league leaders fought back to cancel out Ricardo Vaz Te's 17th minute opener through Antonio Valencia before Mo Diame netted a superb go-ahead go for the Hammers prior to Robin van Persie's 77th minute equaliser.
The draw saw United's lead at the top of the Premier League table reduced to 13 points after Manchester City edged Wigan Athletic 1-0 but Ferguson was not too bothered, preferring to focus on the performance of his champions-elect.
"We had to stand up to a lot, we went down twice but we kept going. We played like champions tonight," he told Sky Sports 2.
"It was magnificent in terms of determination and courage to play.
"It's one more game away...that's five left - three at home and three away. We're determined to win, we don't like losing and they showed that tonight again."
