West Brom boss Di Matteo: Man Utd handed us gifts
United were 2-0 up before the Baggies fought back thanks to two United errors.
"It was an afternoon of gifts," Di Matteo said.
"If Manchester United had got a third the game would probably have been over. But I thought it was a correct result.
"Every game has its own history, so I wasn't thinking about their results, but I just felt if we got one back, it might make them nervous."
