We make the trip to Stamford Bridge with three wins, two draws and just one loss on our travels so far this season in the Premier League.
Roberto helped secure our third league victory in four with the winner against Everton on Sunday and is now looking forward to taking on the unbeaten table-toppers.
“For me, Chelsea are the best team in the Premier League,” said Roberto.
“We are very good away from home and we feel we are a strong team, so we need to continue our away form and keep the confidence high.
“The win against Everton was very important. Why can’t we win at Stamford Bridge? It’s difficult but we will go there to win.”
