The Blues head into the game fresh from their impressive 1-0 win at Arsenal in the Premier League last weekend.
Chelsea have been struggling to find consistent form all season but will be hoping to put together a good FA Cup run in a bid to take their mind of their disastrous Premier League form.
Guus Hiddink has been tasked with steering Chelsea back to form after their poor start to the season led to Jose Mourinho’s sacking last month.
And former Liverpool star Barnes is not expecting the Blues to encounter any problems when they take on MK Dons in the fourth round of the FA Cup on Sunday.
Writing on his blog for Titanbet, Barnes said: “The Dons are doing well in cup competitions, but I think with the way Chelsea’s season is going the FA Cup will have taken real importance.
“Their league campaign looks likely to end in disappointment, so a trip to Wembley will be a way to salvage something and I can see them being motivated for this one.”
Chelsea are currently 13th in the Premier League table.
