I think it doesn't need to wait until half of the season to determine the winner. The winner will be PSG. They recorded impressive statistics from the last three games. They outperform their opponents like nothing. Also, the odds are favoring them to win the competition.
None are able to compete with PSG now. Lille and Monaco can only compete for the UCL spot. They're too far behind compared to PSG. Betting on PSG is always a guaranteed win.
Not only now the PSG be favorite to win Ligue 1 even before the league starts, they have become a strong candidate to become champions this season, so I think there is nothing surprising about their current statistics including consecutive wins at the start of the season, PSG has a squad that is very capable and they are still better than the current rival teams, the quality of the squad and also the financial differences have been a strength for PSG to be able their to easily win Ligue 1, but unfortunately the greatness that PSG have in Ligue 1 is not comparable to their performance and mentality in the Champions League which very bad so far, to be honest if we talk about Ligue 1 of course we can't deny that they are the strongest candidate to be champhionsip, while other teams are currently only competing for a place in the UCL, but for this season Champions League, I personally don't expect much from PSG.
