City drew the Ligue 1 side out of the hat in Switzerland, and Begiristain had mixed feelings when giving his immediate reaction.
He said: "It's always difficult to say whether it's a tough or easy draw, they are doing well in the French league, they have good players, good talent, young players and they are playing some of the best football in France. It's going to be tough, we are happy to be here in the draw, we were in the semi finals last season, so we try to go through.
"Of course the first times we came (to this stage) we played Barca. Real and Bayern Munich, the last winners of the competition... it's always good news to avoid them, but there are others. Monaco topped their group so they are playing well in the Champions League and France - we have to be careful."
