Christian Pulisic was praised by his manager after attending last night's Champions League match against Porto, but those who left did not live up to expectations.
Thomas Tuchel was overjoyed after Chelsea's 2-0 Champions League quarter-final win over Porto, but he admitted that Timo Werner and Kai Havertz did not do well.
"I accept that it was a tough match for Timo and for Kai today, they did not have their best day and we did not deliver so good, 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,"
Tuchel said after the victory .
"To have a bit more of an impact, the balls we delivered were not the best balls. I could feel our two German players up front, Kai and Timo, do not play on their highest level today so I wanted to have an impact from the bench.
"Christian [Pulisic] is in a good moment. Oli [Giroud] waited long and has good experience and memories of this stadium. We wanted to give the sign that we keep on going. This is the general mentality that I like about this club and this team and that we also want to implement.
"It is very hard that once you lead that you do not play with a mentality of now we have something to lose, let’s keep what we have, but just to go and try to win the next half and go and try to win the next duel 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."
