Ajax were the favourite against Feyenoord today but we could have every kind of result in this match. Ajax still were able to defeat them by 2-0 and gained an important advantage against them in the standings. They had a chance to take the lead back and they were the leader temporarily. But PSV didn't make a mistake and crushed Waalwijk by 4-1 and maintained their lead.
You say we could have had any result, but that is not quite true given how strong Ajax currently plays. Yes they did lose a game recently in the league, but they were still the dominant team for almost the whole match. They have just not been fully concentrated for a couple of moments and conceded the goals. Usually they are focussed enough to take those games home.
My favorite team for this year, PSV were on the top stand. It's good if they can maintain until the end of half session next week and win versus Go Head Eagles at home. but on the other side, Ajax won't PSV let go far away from them, of course, Ajax will desperately get the win versus Fortuna Sittard in Amsterdam Arena. I believe PSV is still on the top stand until the finish of half session if be stable like this.
