A controversial penalty handed Juventus a narrow 1-0 win over Monaco in the first leg of their Champions League quarterfinal on Tuesday, leaving everything to play for in next week's return match in the principality.

Arturo Vidal scored his first goal of this season's competition in the 57th minute of an entertaining match after Ricardo Carvalho was judged to have fouled Alvaro Morata in the box.

"It's a great injustice, the penalty was non-existent and I hope that doesn't have an influence on the final result of this tie," Monaco coach Leonardo Jardim said. "I thought we would get a better result. But we showed that we are well organized, that we are a good team and we created a lot of difficulties for Juve.

"I like justice and for me the rules and regulations should be the same for everyone in sport and in life. I'm disappointed... I am convinced the result is due to a wrong decision taken by the match officials."
