Miralem Pjanic says the depth in the Juventus squad is key to ensuring the club keep winning and stay on course for a sixth Scudetto.
For the former Roma midfielder it would be his first taste of success in Italy, having joined the club at the start of the season.
He has so far played his part with eight goals in 26 appearances across all competitions, but realises the closer Juve get to the title, the harder it will be for them to pick up points.
Juventus, who currently lead the Serie A standings by six points over second-placed Napoli, most recently saw off Inter Milan 1-0 on Sunday where Juan Cuadrado scored on the stroke of half-time in a tense encounter.
Pjanic told his club's official website: "We are in great shape at the moment, we are playing some good football and have struck a fine balance between scoring goals and keeping them out.
"Inter made life difficult for us but our home form has always been our ace in the hole. We rarely let things slip and you saw why on Sunday.
"Our squad is deep and packed with quality; when you have strength in depth like that it allows the boss to tailor the starting XI for whatever opposition.
"The most important part of the campaign is just beginning and we need to make sure we are ready for it. The further we go, the smaller the margin for error; the sides behind us will not give up the chase and we must not rest on our laurels."
