If there was one team happier than Benfica last night in the Europa League, then it was French side Lyon who put in an incredible performance to all but guarantee qualification to the next round.
However, it was the Czech based away side, Viktoria Plzen, who were all-smiles in the opening stages after taking an unexpected lead with the first shot on goal.
French U21 international Gueida Fofana scored the equaliser just 10 minutes later to reduce the chances of Europa League shock at the Stade De Gerland.
Liverpool target Alexandre Lacazette then put his team in the lead and on their way to an substantial home victory. The 22-year-old showed good speed, awareness and movement to get onto the end of a Steed Malbranque pass before executing an exquisite low-driven finish into the bottom left-hand corner.
The goal may interest Liverpool manager Brendan Rodgers after the player recently opened the door to a move away from Lyon, commenting: ''If there really is a club that is interested in me and I cannot advance with Lyon, it will be discussed. But I don't think it will come to that. The matter will be talking about between men and discussed intelligently.''
Former Portsmouth midfielder Arnold Mvumba made it 3-1 shortly after and Fofana, the player who started the scoring, also finished it with 20-minutes left on the clock.
The win puts Lyon in a fantastic position going into next week's second-leg in the Czech Republic and will now allow them to focus more on the important league game with Monaco at the weekend.
