It comes after police officers arrested 49 people on Sunday following the Euro 2020 final in Wembley.
Following the match, which saw England lose to Italy on penalties, officers confronted “volatile crowds”.
In a statement, the Met Police said: “Thank you to the tens of thousands of fans who had good spirits and behaved responsibly.
“We made 49 arrests during the day for a variety of offences…
“Frustratingly, 19 of our officers were injured while they confronted volatile crowds. This is wholly unacceptable.
“A big thanks to officers across London and our blue light colleagues for their part in keeping Londoner’s safe and moving tonight.”
