England captain John Terry allayed fears that Wayne Rooney may be distracted against Montenegro on Friday.
The Manchester United forward's father was arrested on Thursday as part of a Scottish Premier League investigation into betting irregularities last season.
However, Terry is certain that Rooney will be able to "switch off" from things outside of football and will be eager to play.
"Wayne’s focused on the game tomorrow," Terry told reporters Thursday.
"I think we all realise the importance of that. It’s important for him to go out there and play his football which he loves doing and he’ll always be fully focused on the football field so that’s all that matters to us.
"When you’re on the pitch and the training pitch you can switch off away from anything in life, but tomorrow’s game is the most important thing and we all realise that and appreciate how difficult the game’s going to be."
The Chelsea captain has a few new player under his wing this time around, as Manchester United defender Phil Jones and Tottenham right-back Kyle Walker are both expected to earn their first caps for country on Friday, and the skipper is looking forward to helping them.
“Yeah, of course, I think that’s part of being a captain [that] when the guys come in the squad that you make them feel at home and welcome, but they certainly [have] come in and expressed themselves on the football field anyway," he said.
"They’re full of confidence and both playing really good football at their clubs as well, so I think they’re very sure of themselves that if they do get the opportunity tomorrow they’ll give a very good performance."
Meanwhile, Terry is unsurprised by the re-emergence of club team-mate Frank Lampard, who, after a slow start to the season, scored a hat-trick against Bolton last weekend.
"I’ve been very pleased but not surprised at all because I knew he could do it," he added.
"At times you do get left out, it tests your character and I think he’s proved all of his critics wrong, which I said he would, and come out and been incredible for Chelsea.
"He's scored some great goals but his performances have been just as good so I knew he would do it and he will continue to do that for a very long time, I’m sure of that."
The 30-year-old defender also spoke of his dream to carry England into a major tournament, a personal ambition he does not confuse with team goals.
"It's obviously my dream to take the England side into a major tournament," he said. "With that in mind, on a personal goal, that’s my target. Collectively the team is the main priority and we must get there."
"Whether that’s a draw or a win we must do the right thing tomorrow.
"We’ve had good preparation, good away form as well, so we’re full of confidence and playing well, hence why we’re top of the group. We must just get ourselves over the line tomorrow."
