The England striker has been on the fringes since the arrival of Tuchel at Stamford Bridge in January.
Abraham has further fallen down the perking order in the attacking options following Tuchel’s decision to play Kai Havertz in the false-nine role, leaving the former Aston Villa loanee out of recent matchday squads.
The 22-year-old remains Chelsea’s top scorer this season with 12 goals but has completed just one match under Tuchel and he has been substituted twice at half time.
Ahead of Chelsea’s visit to East London to face Crystal Palace in the Premier League on Saturday, Tuchel has addressed and explained the reason why Abraham is not getting enough minutes on the pitch.
"Tammy has had a bit of a rough time," Tuchel said ahead of their trip to face London rivals Crystal Palace.
"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. 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.
"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 at the end of the season."
