Real Betis are home to Bayer Leverkusen tonight, both having six points from two games in the Europa League group also containing Celtic and Ferencvaros. If we can all agree that Leverkusen occupy a universe far beyond Celtic right now, catching Betis is the only realistic prospect Celtic have of qualifying for the knock out stage.
That 4-3 defeat in Seville still rankles; we played very well and deserved to go two goals ahead, before a familiar crumble. A point, or more, was possible. So too is a win against Betis in Glasgow, although other results are also a realistic outcome.
If Leverkusen win tonight and Celtic can beat Ferencvaros in Budapest, second place in the group could come down to what we can do against Betis in Glasgow. Of course, there is a case to be made that third place and the Europa Conference, is a better prospect that facing a Champions League dropout team in the first Europa knock out. It is also a lot more likely.
