Problems scoring?

My team usually has problems scoring. Do I have to play with more than 1 striker or something? Usually during matches, we will make more plays, but the opponent defence always stops us, and they can score out of nothing, or sometimes beat my defenders.

Usually my team is stronger.

What's the problem?

1. can be because of engine
2. give them win bonus, they said is working :)
(didn't work for me yesterday)

I do give bonuses. How else can I improve my chances of winning? I really should be winning these matches.

Other ways, give them full moral, condition
