Carlo Ancelotti has warned Chelsea to be wary of a Portsmouth side with nothing to lose in Saturday's FA Cup Final.
Ancelotti's Blues have been installed as overwhelming favourites to win at Wembley and secure their first Premier League and FA Cup Double.
Opponents Portsmouth were relegated from the top-flight following a dismal season, but Ancelotti has cited their semi-final victory over Tottenham as reason for concern.
He warned:"There have been a lot of surprises – Leeds beat Manchester United and Reading beat Liverpool – so we need to pay attention.
"On paper we have more quality and possibility to win but we have to play well. It's a great opportunity to win the Double for the first time but if Portsmouth play better they could win."
Meanwhile, Ancelotti has played down the importance of Chelsea's 5-0 thrashing of the south coast club when they last met in the league back in March.
"We won and played well but at that time they didn't have a lot of motivation but they will on Saturday and it will be a different game," continued the Italian coach.
"We have to have respect for Portsmouth. They were relegated but they deserve to play in this final after beating Tottenham in the semis. We have to fight against them to win this game.
"It is an opportunity for them to save the season. We have to play against players with strong motivation."Subscribe to Football FanCast News Headlines by Email
