Tuchel was asked how they could close the gap to Liverpool, who have now lifted both domestic trophies this term and face Real Madrid in the Champions League final later this month, while trailing Manchester City in the Premier League title race by four points with a game in hand.
"Maybe it's impossible because they are improving their squad in every transfer window they have and it seems like we are losing key players," he explained. "We are of course losing Toni [Rudiger] and we are losing Andreas [Christensen]. It's tough because we already have a gap to close.
"We proved four times this season that we can produce peak performances to compete with them on this kind of level. The difference for me throughout the season is that they can do it on Wednesday again and then they do it on Saturday and Wednesday again, and we struggle.
"They have a bigger squad available. They arrived with everybody except Fabinho fresh and in the rhythm in a final like this. We struggled with three or four players out. N'Golo Kante had one training session at 50 per cent intensity, Mateo Kovacic played with an ankle that I didn't know it was possible you can fit into a shoe.
"They can produce these kind of performances most often and they built this team for many years now and proved it, so this is where the gap is. The sanctions didn't make it easier for us to close it."
