Chelsea v Arsenal live: Carabao Cup latest score and goal updates from semi-final as Ben White heads in opening goal from corner

47 mins: Kepa is quick off his line to clear for Arsenal. Chelsea would like to test their former No 1 a bit more in this second half.

46 mins: Estevao gets us back underway.

Arsenal have scored the opening goal in a 25th game this season.

Will tonight by the 25th time they’ve gone on to win?

Or can Chelsea be the first team to come from behind against the Gunners?

Feint boos from the Chelsea fans; not the first half of football Liam Rosenior would’ve wanted in his first home match as Blues boss.

The inexplicably slow passing from the back is particularly irking the Bridge faithful.

Ben White’s header is the difference at the interval…

And that’s it! Ben White’s header gives Arsenal the advantage, half-way through the first leg of this Carabao Cup semi-final.

45 mins: There will be one minute of added time, as an Arsenal corner comes to nothing due to a foul in the box.

44 mins: Now Cucurella is booked as Saka skips past him and the full-back brings him down. Saka has been fairly quiet so far. That gives him some incentive to dribble at Cucurella in the second half.

42 mins: Audible frustration as Chelsea play out from the back and Sanchez takes his time finding the pass.

But Chelsea do break through, leading to a break for Acheampong. Trossard is booked, as is Estevao, who was complaining to the referee.

40 mins: CLOSE! Chelsea back off Saliba and the Arsenal centre-back thinks why not! He curls an effort just over the crossbar, rippling the top of the netting.

39 mins: Gyokeres gets his head to an Odegaard cross but it loops wide. That was a bit awkward, in fairness. But Gyokeres is not offering Arsenal much and Arteta has both Havertz and Jesus on the bench.
