Back to the action and Celtic continue to struggle for any kind of creativity at Ibrox. In truth, it's been an afternoon to forget from their perspective.

Each time they're in possession, they cough the ball up within seconds. Rangers, a goal to the good, continue to look dangerous on the counter.

Rangers deservedly ahead. Great intensity. They’ve quietened Celtic’s big game players so far. They should be down to 10 (again) though. Flanagan elbow on Brown the most blatant red card. Gets a yellow instead. Odd.

"Jon Flanagan put a forearm in to Scott Brown's face. You just can't do that. Steven Gerrard has been talking about the discipline of his players. He's a very lucky boy to be sent off.'

Oliver Burke pins his ears back and thunders down the right. His attempted cross is cleared for a corner by Katic.

Before the corner is played in, Rangers defender Jon Flanagan is booked for a flying elbow on Celtic skipper Scott Brown.

Could or should that have been a red card?

"Flanagan is a lucky, lucky boy," says BBC Sportsound pundit Neil McCann.

The second half has begun like the first for the visitors... they appear unable to string more than a couple of passes together.

Rangers goalkeeper Wes Foderingham could be leaning against a post reading his Kindle.

I give the credit to Rangers here. Celtic haven't been accurate enough in the face of Rangers' intensity. Rangers' workrate has been sky high. It's reminiscent of the game they won at New Year.

We're back under way at Ibrox. Will we see more goals in the final Old Firm derby of the season?

Celtic have had nothing. It's testament to Rangers' work ethic and their desire to win this game. All the chances have been for Rangers, nothing for Celtic.

Rangers have their noses in front at a sun-kissed Ibrox. James Tavernier's early free kick is the difference between the two sides but the lead could be greater.

Steven Gerrard will be purring at the break; his counterpart Neil Lennon will be stripping paint off the dressing room walls following a toothless display in the opening 45.

Scott Arfield comes within a whisker of doubling Rangers' lead but the hosts will settle for a corner. Meanwhile, Celtic right back Mikael Lustig hobbles off for treatment.

From the corner, Connor Goldson gets his head to the ball but sends his effort over.

Two minutes plus added time remaining of a first half largely dominated by Rangers. The hosts lead courtesy of James Tavernier's early free-kick, as a Celtic shorn of James Forrest look short of width and creativity.

"There are two or three Celtic players that I haven't even noticed. Tom Rogic is one of them. The first time I've really noticed him was when he was giving the ball away. He hasn't influenced the game at all."

Referee Kevin Clancy delays a Celtic corner because of pushing and shoving inside the penalty area. More like two rows of angry ducks refusing to cede water as players from both sides try to engineer some space.

The ball in is eventually cleared by Rangers as the hosts continue to hold a narrow lead at a sun-kissed Ibrox.

More missionary work for referee Kevin Clancy. Celtic striker Odsonne Edouard and Rangers defender Connor Goldson indulge in a bit of handbags after the Edouard chased down a through ball.

Calm restored and we're back under way.
