Team news imminent

And the atmosphere is building around Stamford Bridge.
What's happening with Xavi Simons?
By William Pickworth
There was significant excitement when Tottenham completed the signing of Xavi Simons from RB Leipzig for £52million towards the end of the summer transfer window.
But, as of yet, the Dutchman is yet to dazzle and in some quarters patience is starting to wear a little thin.
So, what has been going wrong?
Well, Daily Mail Sport has tried to find out...
Last time out
By William Pickworth
It was a tale of two halves as a second half dismantling of Nottingham Forest by Chelsea saw off Ange Postecoglou's ill-fated reign at the City Ground.
Enzo Maresca's side badly struggled in the first period, but a triple half-time change by the Italian turned the tide as the Blues jumped up to fifth in the Premier League with a 3-0 victory.
Given the second half display, Maresca's team selection will be interesting tonight, but in the meantime you can catch up with their clash agaisnt Forest below.

Chelsea: The story so far
By William Pickworth
One win and one defeat so far for Chelsea on their return to the Champions League after two years away.
They were beaten 3-1 by Bayern Munich in their opener, which although disappointing, isn't a terrible result given Vincent Kompany's side are arguably the continent's in-form team.
Enzo Maresca's men responded with a 1-0 victory over Benfica as Jose Mourinho returned to Stamford Bridge.
The Blues come in to tonight following back-to-back wins against Liverpool and Nottingham Forest in the Premier League - and they showed signs of their best football during those games.
Ajax currently sit bottom of the League Phase and the Dutch giants are not the side they once were, so Maresca will expect his side to continue their good form.

Tottenham: The story so far
By William Pickworth
It's been an interesting start to the season for Tottenham, who are yet to fully click under Thomas Frank.
They sit sixth in the Premier League and the story has been similar in Europe.
Spurs did beat Villarreal 1-0 in their first game of the Champions League in what was a slightly drab affair, before they fought back from 2-0 down to draw against Bodo/Glimt last month.
Four points from two games is not bad at all, but with matches to come against PSG, Borussia Dortmund and Eintracht Frankfurt in the League Phase, a win would be very much welcomed this evening.
