(Reuters) - Chelsea coach Mauricio Pochettino believes his side should be higher in the Premier League standings, adding that data indicates that their results have not matched their performances on the pitch.

Pochettino's expensive squad have struggled for consistency this season and sit 11th in the league standings with 39 points from 27 games, 17 points fewer than fourth-placed Aston Villa.

Chelsea have a poor goal difference this season but their lack of goals has largely been caused by their own profligacy, with the club ranking fourth in the league for big chances missed.
