Thomas Tuchel stated that he has "no problem" with Phil Foden after the trio did not make the England team for forthcoming matches against Latvia and Wales.
Bellingham has not been recalled even after returning from a shoulder injury, while Foden and Grealish also miss out despite showing a return to form with their clubs.
Tuchel mentioned that the 22-year-old wanted to be included of the selection, having spoken with him on the phone.
"Bellingham is a special player, and for special players there can always be exceptions," Tuchel said about the Real Madrid star, who has made just one start since coming back to full health.
"However we opted to stick with the simple choice of inviting the identical squad.
"Bellingham consistently merits to be here. There is the factor that he has not quite regained his optimal form again at Real Madrid - he has not completed a full game.
"He expressed a desire to be called up. We had a telephone conversation."
The England boss was keen to highlight his good rapport with Bellingham after he said sorry to him previously for calling his conduct during a match as "disgusting" in a televised interview.
Tuchel stated that he uttered those terms "unintentionally" and promised to be more cautious in future.
Inquired if he had any issue with Bellingham, Tuchel responded: "No. There is no issue either with Phil Foden or Grealish.
"Foden is back to impacting and shaping games for Manchester City. Grealish is very close to returning to the top form of himself.
"There is no personal problem."
Saka replacing the injured Noni Madueke is the sole alteration to the previous team, with Ruben Loftus-Cheek and Quansah keeping their spots after being late additions last month due to injury.
The Three Lions face Wales in a friendly at Wembley Stadium on this Thursday before a World Cup qualifier in the Latvian capital on October 14.
If England triumph in Latvia, they will need a maximum of two points from their remaining two matches - against Serbia and Albania in next month - to earn a place in the upcoming tournament in North America.
Strong Performance Under Tuchel
England delivered their best display significantly under Tuchel's leadership when they beat the Serbian team 5-0 away in Belgrade in their previous match.
The coach says that showing made it an straightforward choice to stick with mostly the identical group, though "there exist absolutely no guarantees" for any player regarding selection.
"Our previous gathering was just a few weeks ago and the cohesion and spirit was on the highest level. That is why we decided to call up the identical players to this session," he said.
"Phil is in a very good moment. Adam Wharton merits to be with us. Jones and Trevoh Chalobah are earning playing time with their teams.
"There are players who warrant to be here. Palmer is injured and is a key talent. It will consistently remain like this.
"Is our team a stronger side with Bellingham? Absolutely. But I mentioned before, what do we do if he is unavailable before the tournament? Do we just cancel?"
Tuchel's Media Briefing Gets Noticed
The England manager again delivered a headline-grabbing press briefing.
He, a master of managing his interactions with the press, started with an opening statement to explain his thinking for his decisions.
The midfielder is ready to play and expressed interest to join to camp, but the coach has said he did not want to change the squad significantly after a impressive five-goal victory over their opponents - where the boss noted unity was extremely strong.
But with Tuchel not selecting Bellingham, and his frequent comments about togetherness, it is difficult to avoid link the two - although he said repeatedly how Bellingham is "special" and that there is "no problem" between Tuchel and one of England's star players.
Tuchel has always made it evident that he aimed to make the England squad feel like a club side and, by retaining the identical selection after a big victory, he has achieved that. But the inquiries will come again in the following session if the team win well in these upcoming fixtures.
