Good evening and welcome to the live commentary of the League Cup semi-final clash between Arsenal and Chelsea at the Emirates Stadium.
The two sides played out a goalless draw in the first leg of the contest at Stamford Bridge. The tie remains in the balance, although Arsenal will be aiming to capitalise on home advantage. Nothing has separated the two sides in the Premier League this term, with both matches ending in stalemates, including their 2-2 draw at the Emirates at the begininng of the month.
Without Alexis Sanchez, the Gunners put four goals past Crystal Palace in 22 minutes to secure a dominant victory last time out. The deal sending Sanchez to Manchester United has since been completed, with Henrikh Mkhitaryan moving to the Emirates. The Armenian will not be in action tonight, leaving Arsenal to rely on Mesut Ozil, Alexandre Lacazette and company to steer them into the final.
The team news has been announced and we'll start with the home side.
Chelsea crushed Brighton in their Premier League clash at the Amex Stadium last week. Eden Hazard scored a brace, while Willian and Victor Moses also found the net. Like the Gunners, Antonio Conte's men are searching for reinforcements. Ross Barkley has arrived, but once again must settle for a place on the bench this evening.
Chelsea subs: Drinkwater, Barkley, Zappacosta, Batshuayi, Cahill, Luiz, Eduardo.
Arsenal make only one change from their win over Palace at the weekend. David Ospina replaces Petr Cech between the sticks, with Matt Macey coming on to the bench.
Chelsea make one change from their win over Brighton. Pedro returns from his one-match suspension to replace Michy Batshuayi. Eden Hazard leads the line supported by the Spaniard and Willian in a three-man attack.
STAT ATTACK! This will be the fifth meeting in all competitions between the two sides this season – the third time they’ve met five times in a single campaign and first since 2003-04 (also 1946-47).
STAT ATTACK! All four meetings between these sides in all competitions this season have ended level – the last time two Premier League teams drew four games against each other in the same season was Blackburn versus Sunderland in 2002-03.
HALF-TIME: ARSENAL 1-1 CHELSEA
It remains all square in the League Cup semi-final clash between Arsenal and Chelsea, although the match will not be decided by penalties this evening due to Eden Hazard's strike. The Belgian put the Blues ahead in the seventh minute, converting Pedro's throughball past David Ospina. However, Arsenal drew level when Antonio Rudiger put the ball into his own net, with the Gunners benefitting from two deflections inside the box. Both sides struggled to create after their initial bursts, which will have frustrated Arsene Wenger and Antonio Conte on the sideline.
FULL-TIME: ARSENAL 2-1 CHELSEA
ARSENAL ARE THROUGH TO THE LEAGUE CUP FINAL!
Thanks for joining our commentary this evening. Until next time, goodbye.
Arsenal will play Manchester City in the League Cup final at Wembley. An own goal from Antonio Rudiger and a strike from Granit Xhaka has seen them through after they were forced to come from behind from Eden Hazard's early strike. Arsene Wenger continues to hold the edge over Antonio Conte in their meetings, with the loss leaving the Blues to focus on their battles on three fronts.
