Thanks for your team info above.

Since you have got 4 decent defenders/DMC (cannot play both DL; 5th defender DC is 1* weaker than opponent’s STs, it is not worth the risk of playing 4 defenders plus DMC.

2 approaches that I would suggest:

1) Conservative start & change to aggressive by no later than 30th min if margin is still 3 goals, or 2 goals by half-time

Start: 3-1DMC-4-1AMC-1. Counter on, mixed or long, low pressing & zonal. Back-3 back-arrow. Best MC up-arrow
Change to: 3-4-1-2. Counter on, mixed or long, high pressing & man-to-man

If margin is narrowing to less within the suggested timeframe and scoring is via counter-attack, it may even be better to stick with counter for longer.
Should score with 3-4-1-2, but also very easy to concede.

2) Reverse of above. Start with 3-4-1-2 to hope to score 3 first then revert to counter.

Make sure all starter and likely subs’ conditions are maxed, plus match bonus also maxed.

Wish you the best of luck!
