15:25 CET - Chelsea turned up in the second half to win 3-0 and pile more pressure on Ange Postecoglou.
It was a much-improved performance from the visitors, who relied on two set-piece goals and a bullet header from talented centre-back Josh Acheampong to make it eight winless games for Postecoglou since his appointment.

15:15 CET - It is one hour until Barcelona time in LaLiga! After two setback defeats in the week before the international break, the Catalan giants will be hoping to get their title challenge back on track at home to Girona this afternoon.
The big team news is that Lamine Yamal makes a welcome return to Hansi Flick's side; meanwhile, talented 17-year-old Toni Fernandez makes his senior debut to lead Barcelona's attack.
15:00 CET - There are also two games in Serie A just getting underway as Lecce host Sassuolo and Pisa face Verona.

14:40 CET - After Union Berlin's impressive win last night, the Bundesliga is back this afternoon with five early kick-offs.
The standout of the matches sees third-place RB Leipzig host newly promoted Hamburger SV, and the hosts have the chance to move within two points of league leaders Bayern Munich ahead of der Klassiker this evening.
Elsewhere in the Bundesliga this afternoon:
13:22 CET - It is half-time at the Forest Ground, and the hosts will be disappointed not to be ahead. Chelsea's central defenders were half asleep in the first 30 minutes, handing Forest some great chances. However, the home side failed to take advantage of being on top, and the game remains scoreless.
Encouraging signs for Ange Postecoglou at least.
13:30 CET - The first clash of the big Saturday in LaLiga comes from Seville as in-form Sevilla host bottom-of-the-league Mallorca from 14:00 CET.
