Neil Warnock has spoken of his delight after committing his future to the Boro for another season.
Following meetings with Chairman Steve Gibson, the Boro boss has agreed a deal which will see him remain in charge of the club into 2021/22.
"It wasn't really in doubt," Warnock said.
"I've enjoyed my time here and achieved what I wanted to so far.
"Steve is as big a supporter as he's ever been, and he told me - you've not seen anything until you've seen a full Riverside.
"It'll be great to have the fans back when we can - that's what we all want and it can't come quick enough. You can see a light at the end of the tunnel, but let's be careful until we get there.
"I think we can all look forward now - at my age you know you're not staying on to make up the numbers and I thrive on success, and that's what I'll be striving for."
