I was not surprised by PSG's victory at home to Montpellier even though the score was that high, because in Ligue1 PSG is still really strong and no team has been able to surpass PSG's toughness this season and the same goes for previous seasons. I didn't even expect that PSG would lose to any rival in Ligue1 in the remainder of this season so I really wasn't surprised by the big win that PSG got at home to Montpellier. Moreover, the Montpellier team is a lower ranked team which is quite easy for PSG to beat.
I look at the match schedule for the rest of the season in League 1. I think PSG won't experience any difficulties because their opponents are not that tough, so from now on PSG is a little calm because they only need to develop a strategy to face Barcelona in the Champions League match because PSG's big obstacle at the moment is only that match. Apart from that, PSG can still face it easily. Barcelona has also improved its performance so PSG must carefully prepare themselves before meeting Barcelona.
