The midfielder made his third substitute appearance in the Premier League with an impressive cameo in our 3-1 defeat against Manchester City on Saturday.
He has played eight times in all competitions so far and scored his first goal for the club in the FA Cup draw at Rochdale in February.
Mauricio says there is a possibility for Lucas to feature more if he makes changes to his line-up away to Brighton tomorrow evening (7.45pm).
“Maybe he has the opportunity to start to play a little bit more,” he said at this afternoon's pre-Brighton press conference.
“There are a lot of games still to play and now is the moment maybe to rotate players that are tired. Of course, we need fresh legs to try to get our objectives.
“He is one of the players working hard to try to take the opportunity and maybe tomorrow is a good opportunity for him to play a little bit more.”
