The Mexican striker played against the current Premiership Champions last season in the Champions League for Villareal and he is looking forward to the challenge ahead.
“It was a very good result for Villarreal last season. We played very well and played a very intelligent game,” Franco told the official site.
"I think when you play against Manchester United at Old Trafford; the team has to play intelligently. You can't just defend, because if you give the initiative to Manchester United, it's impossible. We had this problem when we played Manchester United at home, because we sat too deep and gave them the initiative.
"On Tuesday, I think it is necessary that we play intelligently, not sitting back and waiting for Manchester United. I think we have an opportunity to win this game, but if we sit back, it will be impossible.”
