Sevilla vs Man City LIVE: Champions League result and final score as Erling Haaland gets two goals

Chelsea’s Mateo Kovačić spent six years at Dinamo Zagreb at the start of his career and was aged just 16 years and 198 days when he scored on his debut in 2010.

Chelsea are targeting a 100th victory in the Champions League - including qualifying matches - and need just two goals to reach 200 in all-time European away games.

Will they reach these landmarks tonight?

Thomas Tuchel spoke in the build-up to tonight’s fixture about how he believes the home side could cause Chelsea plenty of problems this evening.

“[They have] a lot of individual quality,” he explained. “Up front and on the wings they have speed and dribbling. They will use the role as an underdog to over-perform and make us under-perform.

“This will be their plan. We are aware of that.”

Thomas Tuchel has hailed the “immense boost” of the transfer window being shut and Pierre-Emerick Aubameyang’s tentative steps into Chelsea training.

Chelsea set a one-window British spending record of £273million as new owners Todd Boehly and Behdad Eghbali overhauled the Blues’ playing resources.

New chairman Boehly has acted as interim sporting director, with manager Tuchel holding a key influence on transfer decisions. Barcelona signing Aubameyang was due to start Chelsea training on Sunday, to try out a custom-made protective face mask.

The 33-year-old suffered a broken jaw during a recent home invasion but is determined not to let the attack keep slowing down his start at Chelsea.

Excepting a week in September for an international break, Chelsea will be in midweek-weekend action from now until mid-November as they compete in the Champions League group stages alongside their domestic Premier League games.

This is due to the winter break that will see the World Cup played in November-December this year because temperatures in host nation Qatar are too hot during the summer.

The playing schedule has been adjusted and crammed together to accommodate the tournament moving to winter and such is the intensity that while Chelsea’s group-stage campaign last season lasted 86 days in will take just 58 to complete this year.

This season’s Champions League will feature the use of semi-automated offside technology (SAOT) to reduce delays and discrepancies on refereeing decisions.

Chelsea featured in a trail run for the SAOT during their FIFA Club World Cup triumph and it is hoped that the system can help cut out contentious decisions on the pitch.

It combines the tracking of 29 body parts with the use of a microchip in the ball to help detect offsides that may not be clear on the initial viewing.

On paper Dinamo Zagreb seem to be the easiest opponents Chelsea will face in the Champions League group stages this year but they are by no means easy to beat... especially at home.

The Croatian champions are unbeaten at Stadion Maksimir in 19 matches across all competitions with 16 wins and three draws in that run.

Can the Blues upset their streak or will Zagreb prove stubborn opponents and shock Thomas Tuchel’s side this evening?

Jody Morris believes sealing new long-term contracts for Reece James and Mason Mount could prove Chelsea’s biggest signings of a record-breaking summer.

England wing-back James is understood to be close to completing a new long-term deal to stay at Chelsea, with talks on a similar extension for Mount thought to be progressing positively too.

Real Madrid have had James in their sights as a long-term target, but the Bernabeu giants will see any current designs on the 22-year-old thwarted by Chelsea securing a new deal for one of their brightest talents.

Chelsea spent more than £270m in a record transfer window spree, with Pierre-Emerick Aubameyang the final high-profile addition on Thursday.

Chelsea midfielder Mateo Kovacic started his career at Dinamo Zagreb and played for the club from 2010-13. He says he got a different feeling when returning to his former team with Chelsea for tonight’s Champions League clash.

“As soon as I landed [in Zagreb], I got a different feeling.” said the 28-year-old. “I saw people I haven’t seen for a long time. Only now do I see how much time has passed since I left. It’s a pleasure to play here. I’m a Dinamo fan, but now I’m on the other side.”

Thomas Tuchel says he has invited Pierre-Emerick Aubameyang "to prove a point" following his £10.3m move from Barcelona on deadline day.

Aubameyang has been training in a mask after suffering a jaw injury during a violent robbery at his Barcelona home last week before he returned to London to join Chelsea.

Tuchel says the 33-year-old Gabonese striker has to be "managed" and "needs minutes to get his full fitness and rhythm" because he has only played eight minutes for Barca this season.

The German added: "He cannot play 90 minutes so it’s on us to find a solution if he comes from the bench or he starts."
