By scoring 12 goals in two matches over four days, Manchester United's players are showing they have the firepower to challenge Manchester City for the English Premier League title

The problem is, they don't have the defense to go with it.

United's conceded a goal in the fifth minute of stoppage time to draw Everton 3-3 at home for a result that highlighted the vibrancy of Ole Gunnar Solskjaer's team going forward but the vulnerability of it at the back.

United has the most goals in the league with 49.

But with 30 goals conceded, United has the worst defense in the top 10.

City, on the other hand, has conceded only 13 and goes into tomorrow's showdown with Liverpool with a two-point lead over United and two games in hand.
