Manchester City boss Manuel Pellegrini has down played fears over the fitness of Sergio Aguero after replacing the star striker at half-time during Wednesday's 4-2 win over Viktoria Plzen.
The Argentina international extended his remarkable start to the season by slotting home from the penalty spot at the Etihad to rack up his 15th goal in his last 12 appearances.
Aguero was replaced at half-time by Jesus Navas but Pellegrini revealed that it was always the plan to give the former Atletico Madrid man a rest ahead of Sunday's visit of Swansea City.
"He doesn't have any problems," the Chilean coach told reporters after the game. "He knew from the beginning he was just going to play 45 minutes."
Following Bayern Munich's 10th consecutive Champions League win against CSKA Moscow, it would take a 3-0 win in Germany for City to top Group D and Pellegrini says that overhauling last year's tournament winners is not the priority for his side.
"I think for the moment the Premier League [is more important]," he told Sky Sports. "We are going to play in Munich, we will try to win, but winning 3-0 in Bayern is not easy.
"It's important but more important is the next game [after that] when we play Arsenal."
The English side were twice pegged back by Plzen as first Tomas Hornava and then Stanislav Tecl breached their back line and Pellegrini recognises that his team's free-scoring nature must not see them stall in their defensive progress.
"Always when our team concede goals is a concern for me because we are not doing something well," he remarked.
"[On Wednesday] Plzen scored two goals and had two or three more chances. Last game, CSKA scored [twice]. It's important also to score but we must continue to improve."
