It is quite unusual that we have scored more freely in away fixtures than at home this season and are currently joint top with ManU when it comes to scoring goals in away fixtures but only 14th in the league at home. Looking at our forward players' stats shows that they've all been more clinical when we play away from WHL.
At home:
Bale' had a shot every 17mins with a conversion rate of 8.1% (5 goals from 62 shots over 1080mins)
Defoe' had a shot every 18mins with a conversion rate of 6.7% (4 goals from 60 shots over 1055 mins)
Deuce' had a shot every 22mins with a conversion rate of 5.6% (2 goals from 36 shots over 793mins)
Ade' had a shot every 37mins with a conversion rate of 6.7% (1 goal from 15 shots over 561mins)
Away:
Bale' had a shot every 19mins with a conversion rate of 17.1% (12 goals from 70 shots over 1301mins)
Defoe' had a shot every 26mins with a conversion rate of 13.6% (6 goals from 44 shots over 1125mins)
Deuce' had a shot every 57mins with a conversion rate of 25.0% (3 goals from 12 shots over 684mins)
Ade' had a shot every 44mins with a conversion rate of 7.7% (1 goal from 13 shots over 574mins)
I suppose that this can be partly attributed to our lack of a creative passer (like a Mata, Cazorla, Silva, Carrick, Modric, VdV, Moutinho...) to unlock teams which defend deep and in numbers, so our forwards resort to peppering the goal with long range pot shots. Whilst away from home there's more space to run into which is obviously something our athletic players are better suited to exploiting.

http://www.whoscored.com/Regions/252/Tournaments/2/England-Premier-League shows that we have the greatest proportion of "shots from outside the box" when playing at home with 60% (compared to 31% for City, 34% for ManU, 38% for Arsenal, 42% for Chelsea) whilst away we are 9th with 47%.
