Liverpool midfielder Marko Grujic admits he enjoyed playing for Porto coach Sergio Conceicao last season.
The Serb spent last season on-loan with Porto - and is keen on a return
On Conceicao, Grujic told Sportske: "He won two championships in Portugal in the last four years.
"He also did well in the Champions, we reached the quarter-finals, where we played Chelsea. He [Sérgio Conceiçao] played in Italy, so he added tactical ideas.
"Everyone says that in the next few years he will be one of the main coaches of European football."
He added: "There are many players from South America, we all know how they are. I adapted and in the second half of the season everything went well for me."
