After Effects Edit

1. Split the shot to just before the ball goes in the net
2. Track the ball as it goes into the net on the split part of the shot
3. Create a mask
4. Duplicate the layer, one with jut the ball, one with the hole where the ball was
5. Clone or use Content Aware Fill to fill the hole
6. Cleanup with another copy of the layer rotoscoped and cloned to fill any errors
7. Motion stabilize the just the ball layer, pre-compose, put the anchor point where the ball is
8. Animate the new position of the ball layer
9. Duplicate the shot where the ball goes into the net
10. Isolate just the net on one copy with a mask
11. Distort the isolated part of the net
12. Cleanup the background on the layer under the isolated net so you only see the field
13. When that's done repeat the process on the part of the shot where the goalie blocks the shot
14. Remove the ball for the goalies hand
15. More paint, root, and fixess
16. Render the shot

Mocha Pro would help, but Mocha AE could be used for the roto and the maskiing. It's going to take a lot of work. I do this kind of thing often and if you wanted broadcast quality and were experienced in the workflow it could take you a couple of days. 

That's how you do it. 

In the simplest case you could probably track the ball and attach a different shot of the pitch with no players and a feathered mask. Otherwise you may need to employ elaborate patching with the clone stamp. Anyway, the video quality is too bad to discern anything, so any guess is as good as mine.

I have no idea what you are saying here, since I haven't seen the game and the video quality is terrible, but most likely it was simply lifted from another game. Otherwise it's of course easily possible to construct a fake soccer ball and net and make it wobble e.g. with the Puppet tool or Mesh Warp. the real point simply is that in order to look "real" it will take lots of keyframing and tweaking, but the basic techniques aren't really that difficult.

You mean Ace Ventura screaming in an Argentinea shirt? Or what exactly do you mean?
