Southampton manager Ralph Hasenhuttl says they leave Manchester City with heads held high after their 2-1 defeat.
City trailed to an early James Ward-Prowse goal and did not equalise until Sergio Aguero scored with their first shot on target on 70 minutes, with Kyle Walker hitting their late winner.
Hasenhuttl said: "To come here twice after losing 9-0 is not the easiest moment for a team but I think it was a chance to show up today, and we did, and it was really a pity that we didn't get something for the amazing work we did today.
"We had to show a reaction, we know that Tuesday was the first step and we knew we had to do it better than on Tuesday because the City team today was their first team, their A team, with all their best-performing players.
"And our squad today was unbelievably committed, and unbelievable defending, following the game-plan and investing so much in defending our net.
"It was very difficult today for City to create chances - I don't think they had a lot, only at the end was it open because we wanted the equaliser but until then I think they haven't seen a lot of chances.
"They had a lot of possession, yes sure, that is normal against this team but I think this was the only way how we could play against such an opponent. We did it in a fantastic way."
