I think it is as much dependent on your personnel as your tactics.
For instance lets have a look at our usual starting offensive players.
Saha - defo got a good shot outside the box and has scored a few this season *hang on, wasnt that Chelsea goal outside the box lid? His goal was just inside. [media]http://www.youtube.com/watch?v=k3fdc7GYCzY[/media]
Yakubu - better inside the box than outside of it
Cahill - ditto, his last nine goals have been from headers
Osman - can crack one outside the box (Im struggling but only Stoke this year I think he has achieved that). Been injured a bit.
Arteta - good long shot/free kick on him. been injured a lot.
Pienaar - only found his shooting boots this year, has scored a couple (City & AEK Athens?) Been injured a bit.
Bily - got a shot on him (v United) but has hardly played.
Fellaini - not really.
Heitinga - its more humane to goalkeepers for him not to shoot.
So looking at that, we're a bit average in our human resources for what you're talking about.
What about set pieces as well, did you check that out? We've done alright in that department lid, apart from penalties like.
We have got players such as Arteta, Pienaar, Bily, Rodwell, Baines and Osman who can score from distance. The point I've been getting at is that the number of shots that we have tends to be much lower than the top teams and that, if you don't shoot, you don't score.
Our last 5 games:
City. Shots on Target 3. Shots off Target 3.
Bolton. Shots on Target 6. Shots off Target 7.
Birmingham. Shots on Target 6. Shots off Target 4.
Hull. Skysports don't have the stats for that, for some reason.
Spurs. Shots on Target 5. Shots off Target 4.
Compare that with United.
Liverpool. Shots on Target 5. Shots off Target 5.
Fulham. Shots on Target 9. Shots off Target 14.
Milan. Shots on Target 5. Shots off Target 7.
Wolves. Shots on Target 4. Shots off Target 10.
Villa. Shots on Target 4. Shots off Target 9.
If we exclude their highest scoring game (against Milan) to compensate for us not having the stats for our match with Hull, the results are that we have had 20 shots on target and 18 shots off target. United have had 22 shots on target and 38 shots off target.
The amount of shots on target is very similar. The fact that they've had more than twice as many shots off target as us tells us that they're willing to shoot whenever they get the opportunity. Carrick, Scholes and Gibson will find row z more often than the back of the net, but they might just connect sweetly with one of those shots and end up winning the game with a bolt from the blue.
Think of the amount of own goals that are scored by shots that were otherwise going off target being deflected into the back of the net. 'Own goals' are actually United's second top scorer this season with 10!
