Milan shocks Real to go top
AC Milan came from behind to beat the highly fancied Real Madrid at their own turf and leap to the top of Group C.
This was Real's first defeat in the competition this season and they now move to second on head to head.
Elsewhere, there were home wins for Chelsea, Bordeaux, Porto and Juventus.
Manchester United and Marseille recorded away wins and it was the 14th consecutive away match for Manchester without a loss.
The last away loss for the Old Trafford outfit was a 3-nil loss to AC Milan at the San Siro in May 2007.
This week I take a look at the winning margins so far in the competition:
So the most popular winning margin so far is by one goals and no team has so far won by a winning margin of more than 4 goals.
It would be interesting to check at the end of round 6.
