Are you sure about oppo rates ? I mean are these the final rates (after the game) ?
For that rate of your ST, I would expect a very good rate of his DC (a round 8).
It seems they had many tackles.
Can you post the stats of the game ?

* I would play with your formation/orders
** I also lost today (0-2) in my semi final but it was clear to me why (bad performance of my GK 2/2 shots of oppo, 4 saves and a rate of 8 for oppo GK)
