Snapped up from PSG in January, the Brazilian international showed sparks of his explosive ability in 11 appearances, not least with a goal on his full debut in the FA Cup at Rochdale.
After a tough spell in France, those appearances for us included his first start in the Premier League at Brighton in April – his first league start in almost a year.
“It’s been a very good season for the team and, for me, five months of adaptation,” said Lucas.
“Everything is new for me and I am so happy because it’s a very big club, the structure is fantastic and my team-mates are so good. I’m really happy to be here and looking forward to next season.
“This is the best league in the world with a lot of big clubs and it’s so exciting. It’s different from Brazil or France and for me it’s a dream to play here.
“I think I can improve my game a lot here. The physical side is very different to Brazil and the pace of the game is very different to France. You don’t have so much time to think so I need to decide what I will do with the ball in one second and that’s good for me.
“I have learned from training with my team-mates and I enjoy playing with them. The training here is so hard, we work a lot, and it’s so dynamic. When I have the ball, the defenders come and try to take the ball quickly so I need to improve my game and learn about this kind of football.”
