That could be a major blow to the striker’s hopes of being part of the England squad for this summer’s European Championships – but Tuchel insists his international ambitions will not be allowed to come before Chelsea’s targets.
Abraham remains the club’s leading scorer with 12 goals, but has barely figured under Tuchel. While he has been side-lined with an ankle injury for some of the German’s tenure, even when fit, he has been pushed down the pecking order.
He has only started three league games since scoring a hat-trick in Frank Lampard’s final game in charge against Luton in the FA Cup, twice being substituted at half time.
He is now over that ankle problem but has been offered no guarantees by Tuchel.
“Tammy had a bit of a rough time,” said the Chelsea manager. “He started twice or three times and was twice substituted for tactical reasons at half-time.
“He could not have the impact he demands from himself and we wish from him. Then he was injured and lost a bit the connection and possibility to fight for his place in the squad.
“The squad has played very well without him, we’ve had a lot of results without him. Now we’re in the decisive part of the season where it’s not so easy to bring players who are injured into the shape.
“We have only three changes, which is a big, big thing. It’s a big handicap because three changes most of the time means you only have two because the last one is one you don’t want to lose too early.”
Tuchel has now called on Abraham to force his way into his plans.
He added: “So circumstances are not easy, but it’s on Tammy to do everything possible to let him out. We have a full squad now. We have 22 players on the training pitch and it’s very, very hard to select the 18 players for Premier League matches.
“We can only change three times, but in the offensive position it is always part to have a huge impact in only some minutes. This is very different to the situation of Kepa.
“Nothing has changed. We demand a lot of Tammy, he demands a lot of himself. And he is using every minute to convince us that he needs to be on the pitch. From there we go on and every three days there is a match. “Hopefully he stays fit and plays a key role in the end of the season.”
Abraham now faces a fight to get back into Gareth Southgate’s plans, with the England manager making it clear he wants to his players to be playing regularly at club level before the Euros.
But Tuchel said: “I can’t make my decisions based on the personal goals of my players. Kepa also has the personal goal to go with Spain.
“It’s good they have these goals, but it never influences my decisions. I’m the coach for Chelsea and I have to do what is good and best for us.”
