Chelsea forward Kai Havertz said he would pay for his own travel to away matches while the Premier League club struggles to operate under government restrictions that have impacted its spending.
Chelsea's Russian owner Roman Abramovich was sanctioned by the UK government and the club is currently operating under a special licence.
"I would pay, it's no problem. That's not a big deal for us," Havertz told reporters on Tuesday, with an FA Cup quarter-final game at Middlesbrough coming up three days after its trip to Lille in the Champions League.
"For us to come to the games, that's the most important thing. I think there are a lot of harder things in the world at the moment if we have to take the train or the bus to an away game. I would pay, it's no problem.
"It's not easy. I think such a situation has not happened at Chelsea before, so it's a little bit strange, but we are professionals and sometimes situations like this can happen."
Tuchel had said the European champion had to make adjustments in how many staff are travelling and staying in Lille, where it plays its Champions League last-16 second leg on Wednesday.
The German coach added the need to travel by air was not about "luxury and bling-bling" but about arriving fresh for matches amid a hectic schedule.
"This is just a professional level of sports, where we play with two days between matches with our opponent having four days between matches. And we arrive with the possibilities of injuries," Tuchel said.
"For that, it is better to arrive with a plane rather than a bus."
Chelsea has also asked for the game at Middlesbrough to be played behind closed doors for "sporting integrity" because it is unable to sell tickets due to restrictions imposed by the government licence.
