It came after Gomez was left with a scratch down his face and neck when Sterling accosted him at the start of England’s training camp.
The Manchester City ace subsequently sat out the Montenegro thrashing that saw England qualify for Euro 2020 as punishment.
But after the game he tweeted: “To all the England fans, I wanted to leave things at it was but tonight I have to speak again: it was hard for me to see my team-mate get booed for something that was my fault.
“Joe hasn’t done anything wrong & for me to see someone who keeps his head down and work hard, especially after a difficult week, for him to be booed when he came on tonight was wrong.
“I’ve taken full responsibility and accepted the consequence.
“I felt as though I had to say this, get home safe everyone.”
