Former Barcelona midfielder Xavi believes "there is no reason" Pep Guardiola cannot lead Manchester City to Champions League and Premier League titles this season. After achieving remarkable success at Barcelona and Bayern Munich, the Catalan giant joined City this summer charged with the task of securing the club's place among Europe's elite and claiming more domestic silverware.

Guardiola has got off to a great start, leading City to five wins in their first five league games and beating Borussia Monchengladbach in their opening Champions League match. And Xavi believe the 45-year-old will be a huge success at the Etihad Stadium, insisting he will be out for every title the side can win. "Pep is a winner," he told Goal. "He will want to win it all this season, and with the squad Manchester City have there is no reason he can't achieve that.

"He won the treble with Barcelona and he can win three or four trophies this season. He will want to win it all, of course, the league and Champions League are special - but his ambition will be to win every competition. "Manchester City don't have a second team - it's unfair to call them that. Of course Pep will make changes in the domestic cup competitions, but the players he will be bringing in will be world class international players - that is the strength of the Manchester City squad. You cannot win multiple trophies with 11 players, you need a squad."

And despite the good start City have enjoyed, Xavi has warned the players they will not be given any slack by Guardiola until they are champions. "Manchester City have already established a nice lead in the Premier League, but I know Pep and he will not allow complacency in the dressing room. "They could be 20 points clear - and he would still not allow complacency. Until the league is won - he will insist on full focus."
