Real Betis fullback Emerson admits he's enjoying his football under coach Rubi.
Emerson was brought to Spain in a complicated co-club deal between Betis and Barcelona.
The 20 year-old said, "I feel better now in all aspects, physically, technically, tactically ... I have more confidence in myself thanks, above all, to the support that the coaching staff gives me to do my football.
"Rubi told me in summer: 'I worked with Dani Alves and you have very similar things. I will work with you as I did with him and, if it goes well, I am sure that you will reach the national team.
"When Brazil selected me, I went to his office to greet him and tell him that the objective was fulfilled."
