Have United become too porous?published at 12:50 BST 18 September

There has been so much to like about Dundee United so far this term. However, one source of concern must be the number of goals they have been conceding.
In seven games across all competitions, they have kept just one clean sheet while shipping 14 goals.
If you are conceding around two a game, getting wins becomes a much bigger ask.
In the Premiership, United's eight goals conceded in four matches is the joint highest with Kilmarnock and Livingston, who have both played a game more.
And United's eight concessions have all come from inside the box, suggesting teams are getting in behind them more easily than last season.
Opta data also reveals that in the league United face have faced 24 shots on target - the third highest tally - and two errors have led to goals conceded, while the team are underperforming their xG against of 7.06.
The frailty at the back has at least been countered by the fact they have been prolific at the other end. They have scored 14 goals in seven games and their Premiership haul of nine is bettered only by Hearts.
United have been one of the most entertaining teams in the league this season, a maked contrast to the dogged solidity that was a bedrock of their successful return to the top flight last season.
But will it come at a cost?
