Just had a look at this for you.
I will say that player stats account for quite a lot on this game at the moment, and his squads stats are much higher than yours, pretty much in every position.
Also from experience, 3-4-3 is a hopeless formation. Not much defence, no width.. overall pretty weak in terms of this game.
Also playing conditions and weather suited "continental" playing style, and you used passing.
Tie that in with maybe a "slight" home advantage and a slight aggression advantage (your pansy vs his normal)... and you've got all the ingredients for a bore draw
however with 90 mins advantage you'd expect to have got something from that.
The only thing I could add also is to utilise subs to freshen your squad during the game... I've found I concede less and get more out of a game when I use subs.
Funnily enough that team tripped me up in the friendly ladder last season with similar circumstances... so did not get a friendly challenge this time around
Hope this helps, even if the bitterness of it all still remains!
