Both Chelsea and Arsenal will be looking to earn the bragging rights of their season when they meet at the Emirates Stadium on Wednesday evening.

A place in the League Cup final awaits either Antonio Conte or Arsene Wenger with Manchester City waiting in the wings after they beat Bristol City on Tuesday night.

Here we take a look at the five key things to look out for in this highly anticipated showdown:

#1 Attack v Attack

The first leg may have finished goalless but expect both goalkeepers to pick the ball up from the back of the net on a regular basis this time around. When the two met in the Premier League at the start of this month it was an open affair with the two teams sharing the spoils during a lively 2-2 draw. Add that with a place in the League Cup finals up for grabs then both teams will more than likely step on the accelerator then push on those brakes.

#2 That new technology

The video assistant referee, VAR to me and you, will be on show once again and this time the officials will be hoping it gets positive coverage. There is no doubt that the match referee, on the night, will be using the video referee for assistance. There were a number of controversial decisions made when the two last met at the Emirates Stadium, so expect the fourth official to get an earful from Wenger and Conte once again.

#3 Midfield battle

Passion, desire, tough tackling and some Hollywood passes. This game could be won or lost in the midfield with the workhorse N’Golo Kante coming up against the recently revived Jack Wilshere. Both men will be looking to steer their team to victory but it’s going to be another interesting showdown between the duo in the middle of the park.

#4 Possible tactical tweak from Conte

The Italian has had great success since arriving in the Premier League last season. However, he is yet to taste victory over Wenger. Striker Alvaro Morata and the much-loved Emirates legend Cesc Fabregas will miss the second leg clash through injury. Therefore, Conte could be tempted to use Eden Hazard in a false nine role. The not much-loved Michy Batshuayi did make a rare start during the 4-0 win over Brighton at the weekend, but the youngster has not always been the Italian’s preferred cup of tea.

#5 Watch out for Willy

Willy Caballero is expected to start between the sticks at the Emirates stadium. The Chelsea backup keeper, who has started his sides last two matches, has had a few hairy moments. At times, his lack of playing time has been evident with the Argentinan making a number of iffy decisions in his penalty area. Despite their troubles in defence, Arsenal’s powerful forward line will test Caballero.
