Wigan Athletic manager Roberto Martinez expects Sunday's opponents Manchester City to be in contention to win the title at the end of the Premier League season.
After spending well in excess of £100 million this summer, City have started the season by taking five points from their opening four games, with a 1-1 draw at home to Blackburn last weekend representing a disappointing result for Roberto Mancini.
City did win 2-0 in Salzburg in the Europa League on Thursday though and Martinez feels they have the necessary strength and quality to compete with Chelsea and Manchester United this season.
Asked if he felt City could win their first title since 1968, Martinez said: "Yes, because the Premier League is getting tighter and many teams are capable of taking points off the top four. Chelsea have made a great start, but the season is not going to be decided in the first few months and Man City could easily join that title race.
"They have that strength and talent in that squad. They played one game in the Europa League [on Thursday] and all of a sudden David Silva is back - that is how quickly they can get top players back on form. I just feel City will be in that position when December, January arrives and that is the period when you need to peak.
"We all agree now that Manchester City are one of the glamorous sides in the Premier League, and in European and world football. They have achieved that over the last few seasons with their success in the transfer windows and it is only a matter of time before those players click together as a team and they will be competing for the title, I've got no doubts about that.
"We hope it won't be on Sunday, but we are well aware of their strengths. Certain individuals there are world-class talents and when they click as a team, they will be quite difficult to stop."
