City are debating the Argentine rebel's future ahead of his return to England from a break in his native Buenos Aires having suspended the striker for his alleged behaviour in Germany.
But Barry has urged his club colleagues not to let their own problems unsettle the team in their quest for silverware.
'It's important that players keep their focus and not get too disappointed when they're not playing,' said the England international.
'Everyone has got to stay together and be patient. That's going to be the key to success this season.

'When their chance does come, it's important they take it.'
The 30-year-old admitted the mega-rich club are still on a learning curve but is confident City can compete for the title this season.
He added: 'The club and the squad are still on a learning curve. It's our first real experience of this.
'It's our first season in the Champions League and we are looking to be going on long cup runs as well.
'The players and the whole club are adapting to it and I'm sure we can have a great season.

'If you look at our finishes - fifth in 2010, then third last season when we won the FA Cup - that's great progression.
'If we can keep doing that, then a league title is not going to be too far away.'
Barry will be hoping City can continue their impressive start in the Premier League when they host his former club Aston Villa this weekend at the Etihad Stadium.
