U got no chance in hell mate..ur opposition is way stronger..still to limit damage may be try 5-2mc-2aml/r-1..defensive,counter,own half,down the flanks,red arrows on dl,dr...some might say use hard tackling but that's against the spirit of game as his one of his players might go out injured for long time..it's not ur rival's fault he was pitted against u..and lastly just pray that there's a bug and u might win!!
