BR - Manchester United returned to the top of the Premier League table with a 2-0 win over West Brom, while Manchester City couldn't avoid defeat against Swansea City, and there was plenty on show to learn for both the Red Devils and the Baggies at Old Trafford.
United's goals both came via Wayne Rooney, while Jonas Olsson was dismissed for two yellow cards for West Brom.
Utd are well known for their perseverance, so I think the real thing we have learned is that City now know they are not bulletproof like they thought. Glad to see it! Roll on April 30th, its going to be a cracker!
