Home & Away is a match type in FIFA 21 Kick Off mode, where you can set a two-leg match and play both home and away to determine the winner.
The winner of a Home & Away competition is determined by the aggregate score, which is the team that has scored the most goals from those two matches. If still drawn, the team with the most away goals will be determined the winner.
