Tbh, we don't know whether they will be a threat to us, but on current showing, if they are, we are fighting for 4th place.
They didn't play well, at all, v Everton or Southampton, which are their most recent Premier League games, so why shouldn't people be unimpressed with them ? For decent periods of those games, they got bossed by two of the currently worst, out of form, attacking teams in the Prem & created very few chances themselves. 'Comfortable' they were not. That, plus games v sht teams in the cups, is all we have to go on.
I figured Utd would be our main challengers this season but in actual fact, so far, they don't look good enough, nor as good as Chelsea nor Spurs & it's hard to find a case for them having played better than Liverpool, just had a bit better fortune. Whether that changes I don't know, but it's the truth right now, behind the hype.
I watched a recording of the rags game & CSKA were, in all absolute truth, dogshit beyond anyone has right to be, for a team playing in the Champions League. Celtic would have beaten CSKA by a similar score on the night. They still should have scored more than one goal v the rags though, the openings were there.
It wasn't a game on which to rate the chances of a team regarding challenging for the Prem.
