The 25-year-old touched down in Podgorica on Thursday afternoon to be informed his father, Wayne snr, and uncle, Richie, had been arrested in connection with an alleged betting scam in Scotland last year. They were later released on bail, and Rooney's father tonight protested his innocence through his solicitor.
Rooney has had to deal with off-field issues while on England duty before, notably 13 months ago in Switzerland when he scored in a 3-1 win just as he was being engulfed by tales about his private life.
The Manchester United forward has vowed he will not he distracted as he focuses on his performance on the pitch.
And Terry, no stranger to front-page headlines himself, is confident Rooney will fulfil his pledge as England go chasing the point that will book their place at Euro 2012.
"Wayne's one of the best players in the world," said Terry.
"He will deal with it and go out and perform like he always does. He is fine and focused on the game.
"We all know Wayne, the type of character he is. He'll certainly be okay.
"I don't really want to go into too much detail.
"As players, you learn throughout your career to deal with certain things. The only release is out on the pitch."
Capello has certainly seen the truth of those words in his four years as manager.
As one of the highest-profile players in England's squad, Rooney has often found himself at the centre of unwanted attention.
Rarely have his performances been affected. And he sees no reason why it should be any different on Friday, with Capello believing this matter is not quite as close to home as previous ones.
"He is okay," said the Italian.
"There is absolutely no problem. He is calm and relaxed and I think, in a really short time, we'll find a solution.
"He is in good form and in the last three days he's trained two days really well."
Capello refused to be drawn on the issue of illegal activity in football, and pleaded for patience before conclusions are drawn over allegations.
"It is the job of the police to find out what really happened," Capello said.
"My job, as England manager, is to focus on the game tomorrow."
