Manchester City right-back Pablo Zabaleta believes Sergio Aguero is currently the best striker in the world.
The 26-year-old has scored 19 goals in 20 appearances this season, while his double on Wednesday inspired City's 4-1 win over Sunderland which keeps the Premier League champions six points behind Chelsea.
Zabaleta also feels that Argentina would have won the World Cup if Aguero had not been hampered by his hamstring injury during the tournament given his confident and clinical standards.
"I've known Sergio a long time and I think this is probably the best moment of his career," said Zabaleta.
"Everything he does, he makes it look so easy. He's sharp and clinical. He is also working really hard for the team off the ball. That's something you have to appreciate from Sergio.
"Normally strikers want to play with the ball, but he is working hard for the team and I think he's been great.
"Of course you think what might have been in the World Cup if he'd been fit. You want your top players to be there in their top form. When you have that, you have a lot of chances to win games.
"Unfortunately Sergio had struggled with injuries last season and it continued into the World Cup – but it would have been different with him 100 per cent fit.
"Probably he's the best striker in the world at the moment and we are very lucky to have him in our team. He's been great this season and hopefully he can continue like this."
