Don't underestimate Feyenoord too much because the reality is, Feyenoord this season is also very good in the Eredivisie by only getting one defeat and making Feyenoord currently at the top of the Eredivisie standings. Therefore, in my opinion, it is very unlikely that Feyenoord cannot score against AS Roma because after all, AS Roma is a team that can be said to not have good consistency.
So yes, I personally believe that Feyenoord have a chance to qualify as well, because the odds of 2.00 to 1.75 are not that big of a gap. In fact, it is a fairly close gap, because Feyenoord are also basically not a weak team and Feyenoord still have a chance to beat AS Roma.
The teams are equal, I don't see any great prospects for Feyenoord, Roma can beat them, at least I think Real Sociedad is a stronger opponent than Feyenoord. And of the remaining clubs, Manchester United probably has the most chances to win the title, although Juventus and Sporting are also strong contenders. As for Bayer, I dont know how they can be assessed, they seem to be starting to get in good shape in recent games.
