Despite watching his side pick up exactly from where they left off, Manchester City manager Roberto Mancini is anxiously being left to wait for news on the severity of Sergio Aguero’s injury.
The Argentine striker landed awkwardly on his knee after a pinpoint tackle by Southampton defender Nathaniel Clyne during City’s archetypal leave-it-late 3-2 win yesterday.
And the Italian boss has had a sleepless night on his return to the Premier League after Aguero’s result of a scan has not been revealed.
"I am worried," said Mancini. “We don't know how serious it is because we need to wait maybe two days for the scan.
"But usually the knee is dangerous.
"The injury was so strange because it was not a bad tackle. It was not strong.
"The good thing was that he wanted to try and play. But at the moment we can't say anything."
But the 24-year-old forward – who netted an unforgettable injury-time winner to seal the title for City last season – was more upbeat than his manager last night about facing a potential lengthy sideline spell.
He Tweeted: "The studies I had done revealed there's no significant injury but it was a very tough blow to my knee.
"The physicians will evaluate the time it will take for me to recover.
"I have no words to thank for your concern for me and with this much support, I'll recover faster.
"And I want to congratulate my teammates for their effort in turning this game around. Now more than ever.”
After taking the lead through another South American star striker Carlos Tevez, City were forced to watch The Saints go 2-1 up before Edin Dzeko and Samir Nasri found the net to secure three points.
And restless winger Adam Johnson could be on his way out of the Etihad after struggling to find first-team football, much to the disappointment of Mancini.
"Adam can have a future here but you should also understand when you are 23 or 24 years old, you want to play," said Mancini.
"If you are at a top team, you can't always do that, so I agree, if he wants to, he has to leave.
"But if that happens I will be so sorry because Adam is a good guy.
"He is a different player to the other strikers and wingers and maybe he could be important for us."
