Has anyone found whats the best formation or tactic for fifa15 seasons

Hi can anyone give me some help on defending?

In particular I have trouble stopping people from sprint dribbling right through me, as well as the long cross ball which always lands right on Ronaldo’s foot inch perfect everytime!!

The dribbling I just cant seem to stop,not just when they do it right from KO but in game at times it just seems impossible to prevent. My defenders run along side and apart from slide tacking and giving away a penalty or free kick I just cant get them to tackle or do anything,when they turn my defenders just seem to stand rooted to the spot!! They also seem to auto switch and actually create gaps,although that may be due to me franticly trying to get a defender in front of the attacker !

As for the cross through ball from deep Its more annoying than anything,, but I seem to be getting it used against me more and more.

I am currently in Div 3 and I dont know if its just a step up in op ability or me but I am really struggling,I got relegated back to 4 and came right back up winning all but 2 ,, so its either just the level as I am probably coming up against Div 1 players now,, or its just everyone in this div is better at exploiting all these moves

Does anyone have any tips on how to prevent losing the same kind of goals to these moves? I am still scoring ok just conceding to many now,actually had a 6-5 by half time tonight lol !!

Or perhaps now im in Div 3 the op I am coming up against are using custom tactics etc? I am still just using a default. Has anyone found whats the best formation or tactic for fifa15 seasons

Cheers for any feedback
