Lethal weapon Aguero is back to his best, says Pellegrini

LONDON (Reuters) – Manchester City striker Sergio Agüero is back to his best, manager Manuel Pellegrini said on Wednesday after the Argentine's brilliant header booked his side a place in the Cup final of the League. Aguero rose to fire a superb effort into the bottom corner from 10 yards out to give City a 3-1 victory over Everton and a 4-3 aggregate success in their semi-final clash. It was Agüero's fifth goal in his last three matches, following doubles against Crystal Palace and West Ham United, and it showed his manager that he had fully recovered from the injuries that blighted his start to the season . Agüero, who has now scored seven goals in his last seven matches, has had an interrupted start to the campaign and has been out for seven matches due to a hamstring injury picked up on international duty. After scoring 26 league goals last season, he scored just three of his first 12 Premier League outings in 2015, with Pellegrini facing weeks of questions over when the striker would return to fitness. “Tonight he scored the best goal, a shot that hit the post and he always creates a lot of danger, so I think he is back to his best,” Pellegrini told Sky Sports. City, who will play their fourth major final in the last six seasons when they face Liverpool at Wembley on February 28, were behind for much of the match. They fell behind after 18 minutes thanks to Ross Barkley's superb individual goal and perhaps had the chance to get back into the game when Fernandinho's shot was deflected into the net to make it 1-1 in the evening. Their good fortune continued in the second half when Kevin de Bruyne put the hosts ahead, but only after Raheem Sterling failed to keep the ball in play before cutting it back for the Belgian to head home . The decision to leave the goal standing infuriated Everton manager Roberto Martinez, who was hoping to lead his side to their first cup final in seven years. “Anyone who has seen the replay can clearly see that the ball is out of play,” he told the BBC. “City are a very good team. If they score three goals in the right way then you accept it. The first goal was a deflected shot, but on the second goal the ball was clearly out before it was crossed. ” (Reporting by Toby Davis; Editing by Ed Osmond)
