John Terry has said that Chelsea's squad depth has been a big strength for the club in the Premier League this season.
Jose Mourinho's men side are top of the table from Manchester City on goal difference, with a game in hand, and face Stoke City tomorrow in their second of five matches in 13 days.
The Blues captain told the Sunday Mirror: "They probably don't come any tougher than Stoke away. But we are doing well and it's important we go into games doing the dogged stuff, putting our bodies on the line.
"The strength in depth of the squad [is the difference]. This season we are winning games that maybe we drew last season."
Chelsea have won all eight of their league matches at home this season, while suffering just one defeat away.
