It's very open right now, with both teams pressing forward in search of another goal, so they are leaving themselves exposed at the back.
90' +2
J. Willems enters the game and replaces M. Gaćinović.
Late Frankfurt change, with Gacinovic coming off and he has been replaced by Willems.

There will be a minimum of FIVE minutes added time played.
89'
Frankfurt with a free-kick in a good position after Pedro fouls Jovic, however the ball into the box is poor and the visitors clear the danger.
87'
It's all Chelsea in these final few minutes and there isn't long left to play now, but they are making a few mistakes at the back which is giving Frankfurt hope of a winning goal. Jorginho loses possession after a poor pass to him by Kepa on the edge of the box and Kostic breaks free in the area, but luckily David Luiz gets back to make the block.
83'
M. Kovačić enters the game and replaces R. Loftus-Cheek.
Another Chelsea change now as Loftus-Cheek makes his way off the pitch and he has been replaced by Kovacic.
81'
The home supporters are still urging their side forward and Paciencia goes close after Da Costa cuts in from the right wing and drills a ball across the face of goal, but Paciencia just can't quite get there in time and it goes out of play. The linesman has his flag up for offside, but after looking at the replay it appears to be the wrong decision.
77'
Another good save! Trapp this time has to be alert to stop David Luiz from scoring, after the centre-back glanced on a cross into the box and tried to place the ball into the far corner of the net. The Frankfurt keeper has had plenty to do in this second half.
73'
Gonçalo Paciência enters the game and replaces G. Fernandes.
Frankfurt now make their first change, with Gelson coming off and he has been replaced by Paciencia.

Giroud has been more involved since Hazard came onto the pitch, the striker has scored 10 goals in this competition so far this season.
69'
Still no Frankfurt changes, despite there appearing to be a few tired players out there now after having to chase the ball for nearly all of the second half. They haven't threatened in attack themselves.
67'
Hazard has been heavily involved since coming onto the pitch, drifting across the Frankfurt backline and troubling the hosts defence, who just can't get a touch on the ball at the moment.

It's all Chelsea at the moment, with Frankfurt sitting deep inside their own half and they have everyone back behind the ball defending.

HALF-TIME: FRANKFURT 1-1 CHELSEA
45'
Pedro has scored a goal for Chelsea! Assist by R. Loftus-Cheek.
Loftus-Cheek works his way past a couple of Frankfurt defenders and looks to go for goal himself, but he spots Pedro in a better position, who produces a fine finish.
GOOOAAALLL! Chelsea equalise right at the end of the first half, it's 1-1! It comes from a corner that Frankfurt don't deal with and Pedro shows great quick feet in the box after David Luiz and Loftus-Cheek link up well. The ball is laid it off to Pedro and the Spaniard fires it into the far corner of the net, just out of the reach of Trapp.
44'
Chelsea are really pushing forward here at the end of the first half, they have Frankfurt camped inside their own half and the visitors are starting to threaten in front of goal.
42'
Close! Loftus-Cheek isn't too far away there! The midfielder drifts into the box, he manages to get away from his marker and then fire a low shot towards goal, which goes just wide of the post.
40'
There's not long left to play until the break now, can Chelsea find an equalising goal before the break, or could Frankfurt extend their lead?
38'
Giroud is down in the box and appeals for a penalty, but the referee awards a free-kick to Frankfurt instead after the striker had a hold of Hinteregger's shirt.
37'
Now it's Frankfurt's chance to test their opponents with a couple of corners, however, the second corner is taken short and then the ball into the box fails to beat the first defender. Chelsea break up the other end and Pedro wins a corner!
35'
Chelsea win a couple of back-to-back corners, but the hosts defend them well. The Blues haven't forced Trapp into making a save yet, they are struggling in the attacking third.
33'
A few handball appeals from Chelsea players as Giroud's flick on appears to strike the upper arm of Abraham right on the edge of the box. However, the Frankfurt skipper didn't know anything about it and the referee waves away the visitors protests.
31'
Frankfurt have dropped off now, they are letting Chelsea have the ball in their own half and allowing them to pass it around. However, as soon as they get close to the hosts half, they are pressing high.
25'
Frankfurt had been starting to dominate the last few minutes before going ahead, showing more urgency to push forward and they look full of confidence now.
23'

Kostic whips a cross into the box, which Jovic dives onto the end of and places the ball into the far corner of the net with a header, just out of Kepa's reach.
19'
A. Christensen gets yellow.
No complaints with that yellow card, Christensen slides through the back of Rode, he's late and takes the man, getting nowhere near the ball.
18'
Good move! Frankfurt work the ball into the final third and stretch the Chelsea defence with quick one-two touch football. The ball is eventually laid out wide by Hinteregger to Da Costa, who tries to square the ball to a teammate in the middle for a tap-in, but Kepa reads it well and makes the save.
16'
Giroud hasn't touched the ball much so far, he's just been on the receiving end of a tough tackle by Hinteregger on the halfway line, which could've been a yellow card.
14'
The pace of the game is quite at the moment, as both teams feel their way into the match and try and carve open the first opportunity of the game. Neither team is keeping possession very well, so it's very open.
12'
The atmosphere is electric inside the stadium, with the home supporters making a lot of noise and booing and whistling everytime a Chelsea player touches the ball.
8'
Good move by Frankfurt, they almost work space for a shot inside the Chelsea penalty area, but the Blues just manage to get players back in time. A deep cross then comes into the box from the left wing, which looks to be heading straight out of play for a throw-in, but Gelson fouls Emerson close to the touchline.
6'
Rode almost gets caught out on the ball deep inside his own half, with Kante and Jorginho both hassling him and eventually bringing him down and Frankfurt are awarded a free-kick.
