LONDON: Thomas Tuchel warned Chelsea their League Cup semi-final against Tottenham is not over yet after they took control of the tie with a 2-0 first leg win on Wednesday. Tuchel’s side are within touching distance of a first League Cup final appearance since 2019 after brushing aside Tottenham at Stamford Bridge. Kai Havertz put Chelsea ahead with a deflected strike before Ben Davies’s farcical own goal increased their lead before half-time. Although Chelsea were unable to completely kill off their London rivals, they head to Tottenham for the second leg on January 12 as firm favourites to reach the final against Liverpool or Arsenal. Liverpool’s semi-final first leg, scheduled for Thursday, has been postponed until next week after a significant coronavirus outbreak among Jurgen Klopp’s squad. Chelsea’s victory was their first in three games, building on their spirited fightback from two goals down to draw 2-2 against Liverpool on Sunday. “It seems like a deserved win, an excellent result because it reflects the game. We could have scored more but it is hard to score against Tottenham,” Tuchel said. With Romelu Lukaku back in the fold, albeit once again looking far from his best, Tuchel will hope he has navigated a storm that threatened to derail Chelsea’s season. Lukaku, Chelsea’s club record £97.5 million ($132 million) signing from Inter Milan last year, was dropped for the Liverpool game after he gave an interview that featured criticism of the way he was being used by Tuchel. But Tuchel said he held “calm” talks with the Belgium striker on Monday and restored him to the team to face Tottenham after he issued an apology. “Romelu can handle pressure and adversity, it was a good performance, he contributed a lot to our defensive set up and had chances.” ‘It was a difficult game’: Ironically, Lukaku’s return came against Tottenham boss Antonio Conte, who got the best out of him during their Serie A-winning spell together at Inter. Conte was back at Chelsea for the first time since being sacked in 2018 despite winning the Premier League and FA Cup in his two-year reign. The Italian claimed earlier this season that Chelsea had yet to work out how to get the best out of Lukaku, but he has plenty of work to do with his own team on the evidence of Tottenham’s spluttering display. Lukaku was greeted with surprisingly little venom from the Chelsea fans, a reception perhaps helped by their side making the perfect start in the fifth minute. Japhet Tanganga played Emerson Royal into trouble deep inside the Tottenham half and Marcos Alonso pounced to steal possession. Alonso slipped his pass behind the out of position Tanganga to Havertz, whose close-range shot deflected in off Davinson Sanchez for his first goal since November 6. Although Chelsea were without Thiago Silva and N’Golo Kante after they tested positive for the coronavirus, the European champions dominated from start to finish. Lukaku had a role in Chelsea’s second goal in the 34th minute as his persistence drew a foul from Sanchez. Hakim Ziyech’s free-kick should have been easily dealt with by Tanganga, but the hapless centre-back headed it straight at Davies, who had no chance of getting out of the way as it rebounded off his shoulder into the net.
