Frankfurt come close twice!! Kepa makes a good save with the first one before a second attempt goes wide.
58'
Sebastian Rode is lucky not to receive a second yellow card for a very poor challenge on Loftus-Cheek...
55'
Willian plays an excellent ball in, but a good header prevents what would have been an easy chance for Giroud...
52'
So then... As it stands, we are heading to extra time at Stamford Bridge, Frankfurt have never stopped working and they rightfully are completely level.
51'
Giroud comes very close to giving Chelsea the lead straight away! He sends it too far past the left hand up right and it remains 1-1.
GOOOOOOOOOOAAAAAAAL! Luka Jovic has changed this game BIG TIME! David Luiz is once again at fault with some very questionable defending...
46'
We're back underway at Stamford Bridge, no changes from either side at half time.
45'
HT: Chelsea 1-0 Frankfurt (2-1 on aggregate). Chelsea are looking comfortable so far here in London, Loftus-Cheek scored a deserved goal on 28 minutes, and Chelsea could have had more, Frankfurt could have scored too though and are certainly not out of this game yet.
40'
Chelsea earn a corner after Loftus-Cheek has an effort that almost makes it 2-0, he is having a fine game for the London club.
Falette is yellow carded for a poor studs up challenge on Willian, the Brazilian winger is not happy about it either...
34'
Chelsea looking to take full control of this tie with a second goal, they've been good for their lead tonight and probably deserve a second goal.
29'
Of course from a Frankfurt point of view, nothing has really changed, a goal for them will take this to extra time, and should they score twice, Chelsea will need to score two more....
GOAAAAAAAAAAAAALLLLL! Ruben Loftus-Cheek gives Chelsea a deserved lead at Stamford Bridge! An excellently taken finish into the bottom left corner and Maurizio Sarri goes wild, Chelsea have one foot in the final...
23'
CLOSE! Olivier Giroud comes very close to giving Chelsea the lead, Emerson with an excellent cross into the box, which Giroud hits at Kevin Trapp who does very well to save it.
21'
There's a bit of a sense of general nervousness at Stamford Bridge, Chelsea's inconsistency has been a problem this season, however, they have only lost two games all season at Stamford bridge and they are unbeaten since 2013 in the Europa League...
18'
Chelsea appear to have recovered from that scare after the fierce volley was saved by Da Costa, to think that Frankfurt lost 6-1 at the weekend away at Leverkusen, they are doing their incredible away support a lot of justice so far.
14'
WHAT A SAVE! Kepa makes an extraordinary save to deny DaCosta what would have been an incredible goal! Frankfurt starting to gain some footing here though...
13'
Frankfurt have a free kick which is comfortably dealt with by the Chelsea defence.
10'
A ball is played through for Hazard but he cannot get a touch on it, should this be the Belgian's last ever match at Stamford Bridge, he will be looking to deliver some performance.
7'
Chelsea are dominant in this game at the moment and are keeping all the ball, they of course do not need to score tonight to progress to the final in Baku.
4'
Frankfurt have a corner and danger man Luka Jovic is the man who gets to it! It is a simple save for Kepa however as it is straight at him.
2'
Emerson has a good run up the left hand side, but ends up taking one too many men on and gives a foul away when trying to get it back.
1'
We have kick off at Stamford Bridge!
Start of match
PRVW
The teams are out at Stamford Bridge, Chelsea at the moment will be progressing on away goals, we shall have to see if it remains that way in 90 minutes!
PRVW
Meanwhile, Frankfurt lost 6-1 against Bayer Leverkusen at the weekend, a result they will be looking to avoid again tonight, as they look to bring back a second trophy in as many years.
PRVW
After the recent Champions League drama involving English sides, I'm sure Maurizio Sarri is hoping for a much quieter evening, as long as Frankfurt do not find the net, Chelsea will be progressing to Baku.
