Sport Chelsea boss Tuchel explains Havertz and Werner subs: They didn't have their best day
Abramovich pushed for Havertz deal and he is FINALLY flourishing
Frank Lampard was unable to find the solution, deploying Kai Havertz in numerous positions. However, Tuchel appears to be on to something with Havertz and it could be worth persisting with.There have also been suggestions that he was effectively bought for Chelsea as a gift from Roman Abramovich.
Chelsea head coach Thomas Tuchel admitted Kai Havertz and Timo Werner were replaced following underwhelming performances in Wednesday's Champions League success against Porto.
Mason Mount and Ben Chilwell scored as Chelsea drew first blood against Portuguese outfit Porto in the quarter-final tie with a 2-0 victory in Seville midweek.
It was a necessary response for Tuchel, whose 10-man Chelsea were sensationally humbled 5-2 by lowly West Brom in the Premier League last time out.
But Chelsea did not have it all their own way against Porto, who were the better side for periods of the game and only just second best in terms of expected goals (xG) – 1.8 to 1.7 in the former's favour.
Chelsea 'do not plan on selling Timo Werner this summer'
Werner has played a bigger role since Thomas Tuchel took over from Frank Lampard and there are currently no plans to offload the 25-year-old - not even as part of a deal to sign Erling Haaland.Werner only moved to Stamford Bridge last summer for £47.5m from RB Leipzig but has struggled in his first season in English football, scoring just one goal in his last 20 Premier League games.
Havertz and Werner particularly struggled, the German duo replaced by Olivier Giroud and Christian Pulisic with 25 minutes remaining, and Tuchel explained his changes.
In his last 29 games in all competitions, Werner has missed 20 big chances, with an xG of 10.5 and 3.5 shot conversion rate.
"I accepted that it was a tough match for Timo and for Kai today," Tuchel told reporters after Chelsea won consecutive away knockout fixtures in the Champions League for the first time since 2004. "They did not have their best day but we did not deliver so well [for them].
"The connection between the deep seven players that we needed for the build-up and the front three, we lost a bit the connection to them.
"The balls we delivered were not the best balls and I could feel our two German players up front, Kai and Timo, did not play on their highest level today so I wanted to have an impact from the bench."
Pulisic suffers injury which forced Tuchel to change second-half plans
With Chelsea 2-1 down at half-time, Thomas Tuchel had planned to bring off Timo Werner, only for Christian Pulisic to immediately pull up with an injury and change his plans.The German manager suffered his first Premier League defeat with the Blues who were left stunned after a 5-2 loss to West Brom.
No side has conceded fewer goals (two) or kept more clean sheets (seven) in this season's Champions League than Chelsea (level with Manchester City on both counts).
Since Tuchel's first game in charge of Chelsea (January 27), no goalkeeper playing for a top-five European side has kept more clean sheets in all competitions than Edouard Mendy (10).
Tuchel added: "Christian has a good momentum, Oli has waited long and has good experience and memories of this stadium. We wanted to give the sign that we keep on going [in the game].
"This is the mentality in general that I like about this club and this team and that we want to implement. Once you lead, it is very hard to not play with the mentality of having something to lose. You want to keep what you have.
"But you need to go to try to win the next half and go and try to win the next duels and try to score the next goal. The best way to defend is to attack. The best way to impress the opponents is to have ball possession to be couraged and to always be a threat.
"I am happy about the impact of our substitutions. It is absolutely necessary that we have this bond between the players and we have this impact from the bench physically, but also with quality. That's why we are super happy with a big win today. The job is half done and we are aware of that and we need another top performance on Tuesday."
Kai Havertz delighted to have got on the scoresheet for Chelsea .
