Manchester City manager Pep Guardiola praised RB Leipzig's fearlessness after their Champions League group stage match on Wednesday.
The Germans kept fighting when City went ahead, eventually getting the scores to 4-3 before Guardiola's side ran out 6-3 winners.
"Leipzig never give up. They have a special way to attack. They play all or nothing," Guardiola said.
"You never have the feeling it's over. We scored a few minutes after they scored [a few times] and it helped us a lot.
"They have a young team, so aggressive, so strong. A fantastic team. Leipzig give a good message to football. The quality of the players was better today and that's why we won.
"We scored 16 goals in the last three games here. I'd like more people to come on Saturday. We will be tired. Southampton are so dangerous. I invite all our people to come 3pm to watch our game."
