Manchester City striker Sergio Aguero is determined not to let standards slip ahead of Sunday's trip to Saints, as he bids to get the club's season back on track.

Aguero scored a sensational hat-trick against ten-man Bayern Munich on Tuesday to revive City's hopes in the Champions League.

The prolific Argentinian took his goal tally for the season to 17, as he followed up an early penalty by striking twice in the last five minutes to hand City a dramatic 3-2 win at the Etihad Stadium.

It was City's first victory in the competition this season and keeps alive hope of reaching the last 16.

Aguero will also hope to maintain his form as the defending Premier League champions, who are eight points behind leaders Chelsea, travel to second-placed Saints, who are two points ahead of them, this weekend.

Aguero said: ''It was important to win. Apart from my goals the three points were vital, so we're delighted.

"I am happy with my form. This season things are going well for me and it is important to carry on like this and keep the results coming.''
