#4 Roberto Firmino (1899 Hoffenheim to Liverpool)
Ad

The Brazilian striker was in red-hot form for the German club when he was considered for the role of a striker at United. Bobby Firmino had to reject the move due to his concerns about Manchester United's style of play.
He later signed for Jurgen Klopp's Liverpool, and also netted a goal in the Champions League final last season. He has now become Liverpool's main striker, and also represented Brazil at the World Cup.
