Watford winger Miguel Layun was delighted to be part of Porto's shock Champions League win over Chelsea.
The Mexico international was a late second-half substitute in the 2-1 triumph.
"This is what I wanted when I signed for Porto.
"It is something very special. There are not many opportunities in the career of a player to play in this tournament," Layun declared.
"We played an intelligent game, pressing Chelsea all over the pitch."
