Guidolin says he is not worried about Llorente's lack of goals this season and insists his Swansea team must improve if his strikers are to start scoring.
"I'm not frustrated about Fernando because this is his first time in the Premier League and at the moment he plays strong for the team," Guidolin said.
"I am sure when we improve our way of playing it's not a problem for Fernando to score because he's a good player. The team has to improve - and the team can improve.
"If we play better, there will be more opportunities to score for a striker like Fernando."
