I'm convinced that 3W at defense is a really bad idea. Make him pay for that. put 2 STs and play wide to take advantage of your strong fullback. I think your goal should be to outnumber him when you attack. Your ML/MR should be marked by his fullbacks and then with just 1 DMC and 1 DC against your STs he must be in trouble.

If you decide to play with 1 ST play very narrow and outnumber him at his own half by putting 2-3 AMCs at narrow formation.

Otherwise make your ST to count. Force him ti face your ST at one on one situations with his DC. Therefore, put an extra man as AMC and attack down both flanks to keep busy his fullbacks.

I think even a 4-4-2 should do the job just fine.

Since he's stronger maybe hard tackling is ok.
Consider pressing him whole pitch, since he defends only with 4 on a very strange formation. (3W-1 (!) really?)
