Chelsea fullback Davide Zappacosta says the players know how important their clash with Watford now is.

Chelsea need a win after their shock defeat at Crystal Palace last week.

"We are 100 percent aware that it is very important we improve our performance at home and we know also that we have our fans to support us at home which basically represents a 12th man on the field, and I am confident that we will manage to improve that home form," said the deadline day signing.

"Watford have started very well, they have put some good teams into difficulty but we are confident we can take three points and we are going to do our best to do that.

"The injuries [we have had] are not good for the team because we are losing some important players,' Zappacosta added, 'but all the players Chelsea have are really good players and they will give 100 per cent whenever they are called to take part in the team, and we need to give 100 per cent and try to overcome this rough patch.

"We are preparing for this game like all the other games, with maximum concentration and our manager is looking into every single detail. That is very important for us so we can tackle any potential problems in the best way possible."
