Vincent Kompany believes Manchester City has progressed, after sealing a win in the opener against Brighton.
Brighton held strong in defence against attacks from Manchester City and fell to a goal from Aguero late in the second half.
A second goal came for Manchester City to put the game beyond doubt on their first game of the season.
The skipper told BT Sport : “We had to be patient first half, they were defending really well. They were organised and you could see they had a clear game plan, but we’ve got quality and eventually it made the difference.
“Talking about attacking options – we know it in training of course because we have to face [Aguero] every day.
“But the season is going to be long and today was an improvement on a lot of things we did last season.
“We had a five-minute spell where we were under pressure. We put our bodies in, we made some important tackles and eventually we got the goal because we were patient.
“Ultimately [we have] a lot of positive things to take from this game and we kind of built on the pre-season we had.”
