Manchester City manager Mark Hughes has warned the Premier League's 'big four' they will continue to drop points.Hughes's side kept up the pressure at the top of the Premier League after drawing at Wigan on Sunday and are five points off the top with a game in hand.
Chelsea and Liverpool lost on Saturday and Hughes feels they, along with Manchester United and Arsenal, will see their dominance challenged this season.
"This year has the potential to be as open as it has ever been," said Hughes.
"The top four teams will drop points. That has been evident at the beginning of the season and it will continue."
City spent over £100m on new players during the summer and have already beaten Arsenal this season, while Tottenham are already mounting a strong challenge for a top-four finish and a place in next season's Champions League.
With Aston Villa beating Chelsea on Saturday and Sunderland defeating Liverpool, Hughes feels the overall standard is higher this season.
"I just think there are more good teams in the top half of the table that can cause problems for the sides around them," said Hughes.
"What everyone is trying to do is get into a position by March or April where you are still in contention and you can be a factor.
"There are going to be a lot of games of real significance at the end of this season rather than it just petering out really for some teams. That has to be good for the Premier League."
Hughes's side had to come from behind to earn a point at the DW Stadium on Sunday and did so despite being reduced to 10 men.
The Welshman was delighted with the character shown by his side, saying: "Last year we would have struggled to get a point here."
"But we are different group now and we have the mentality you need to dig in when things are going against you and get something out of a game.
"Who knows how important this point will be in the shake up at the end of the year. What we have to make sure we do is get something from every game as it's going to be wide open this season."
