We have bad home form this season..What should Scolari do?

cfloo

Chelsea 1 - 2 Arsenal
Chelsea 0 - 0 Newcastle United
Chelsea 1 - 1 Burnley
Chelsea 0 - 1 Liverpool
Chelsea 1 - 1 Manchester United
Chelsea 1 - 1 Tottenham Hotspur

Is it any way to defeat team who came to Stamford and play defence for whole 90 minutes?

What should Chelsea do to win this games?

Can Drogba help us to win our home fixtures?

Is it players fault, Scolari or maybe something else?
