Gloucester born and bred, it was evident when he spoke to the media that defeat really hurt.
"The boys are very disappointed. We just didn't deliver. Our small skills were wrong, we lost too much ball around contact, fell off a few tackles. It's just not good enough really."
"If you play a team and put in a good performance and get beaten, you can accept it but days like today are hard to take."
The freezing weather has seen two of Gloucester's fixture postponed in recent weeks so the usual week in and week out routine has been disrupted but the 32 year old refused to use that as an excuse.
"The last month or so has been really disjointed, with training moving around different venues etc. But it's the same for a lot of teams. We've just got to get things right mentally because rugby is mental as well as physical."
"It was lots of little things against Leeds, loads of individual errors that collectively just built up. Contact wasn't good enough, we lost a lot of ball in rucks - whether there were hands in there or not, we've got to deal with it."
Exeter are the visitors to Kingsholm this weekend and Hazell recognised the challenge that lies ahead.
"Exeter have got a dogged, workmanlike back row so we've got to get our heads right for that. They're a tough team, they'll tackle all day and we'll have to be prepared to roll up our sleeves and get stuck in."
"We've lost two on the bounce and it's not good, we're not happy about it."
"We know what we're doing and it's been little things that add up. They've crept into our game and we've got to phase them out."
"The frustrating thing is that we know we've got the team to do it. There's a good feeling in the camp and the boys are training hard but little things are letting us down."
"It's annoying but there's still a long way to go yet."
