Manchester City boss Roberto Mancini has played down their free-scoring ways.

If City continue to score at their current pace, they would clock up 138 goals for the season - Chelsea's Premier League record of 103 in 2009-10 could be under threat.

Yet Mancini is sure his men will slow down sooner or later and said: "To keep going at this rate is impossible!

"You know that the records are there - a team will probably beat the record but I think this is very difficult."
