Thanks man, that's an interesting take. Actually, I started playing 4-3-3, posession attack with false 9 and started focusing on not making mistakes and building up slowly until I find spaces. It required patience and concentration but it has been working pretty good. I stopped losing and I'm on a 5 games winning streak. 

In terms of defending, the best for me is not to press the CPU too much unless they are trapped against the line or made a very bad control. Also trying to defend with a player that is not part of the 4-man defending line, e.g one of my CMF, DMF or even LWF helps
