Aguero's second-half goal helped City regain top spot - a point ahead of challengers Liverpool - with two matches of the season left.
Argentina striker Aguero put City ahead when his close-range effort was deemed to have gone in by goalline technology despite a last-ditch clearance by Matt Lowton.
Aguero stated at the final whistle: “I am so very happy for the win and now we have one week now to prepare for the next game.
“I think it was over the line! I am very happy with the goal because the first half we had chances. I was happy for the technology.
“When I scored I enjoyed the moment with my team-mates."
