Rayo Vallecano midfielder Piti has urged Leo Baptistao to reject interest from Manchester United.
United chief scout Martin Ferguson made a check on Baptistao this week.
"Leo is tremendous. He gives us a lot because he loves to beat players, score goals and more," he said.
"The truth is we can not ask for more off him, he can only continue to impress. He is very focused and wants be even better but I just hope that he stays with us all season."
