The Brazil international is desperate for the wantaway striker to remain at Anfield, while revealing his own happiness at the club
The Uruguay international has publicly expressed his desire to quit the Premier League after suggesting negative press coverage surrounding his controversies has had an impact on his private life.
Suarez, who scored 30 goals in all competitions for Liverpool last season, also claimed it would be a "dream" to secure a move to Real Madrid.
"Luis Suarez has influenced many matches for us, and is a player, if he leaves, who would be a great loss," Lucas told Radio Grenal.
The Brazil international insists he is content with his own future at Liverpool but concedes Brendan Rodgers' side will not be considered favourites to win the Premier League title next season.
"It's been six years and I am very happy at Liverpool," he continued.
"If I fulfil my contract until the end, would be 11 years at Liverpool. Here in Europe I feel more complete than when I arrived at the club. I have evolved a lot with the coaches who have passed through here.
"The favourites to win the Premier League title are [Manchester] City, United, Chelsea, Arsenal and even Tottenham."
