I haven't followed this season as closely as the last few seasons, but Ajax have now won a total of 7 games in a row in the league, so they're already picking up a lot of points. Contrast that with PSV with three draws and one loss in their last 5 games. If Ajax's form continues, it will be difficult for PSV. Everyone else is already too far away for the title, in my opinion.
Ajax is in great form. PSV, on the other hand, has become very bad later on. They started the league very well but could not continue. Ajax is currently in the lead despite playing one less match. If they complete their missing match and win, the point difference between them and PSV will increase to five. Ajax seems to be the strongest candidate for the championship this year. As long as PSV continues to regress in the game they play, Ajax may even reach a higher point difference.
Ajax are 2 points ahead of PSV with 1 game in hand, yes if Ajax can win that game and continue to perform consistently they can definitely top the standings continuously and really win the title.
Today Ajax suffered lost from Union Saint-Gilloise for the second leg of the Europa League but they are still ahead on aggregate because of their winning in the first leg, unfortunately Ajax had to get 1 red card received by Davy Klaassen and for the last 16 match later he will definitely be absent due to playing suspension.
