Arsenal striker Thierry Henry insisted there must be an end product to the Gunners' record-breaking run.
As Arsenal equalled Nottingham Forest's 42-game unbeaten League run Henry said: "Even on the pitch we didn't realise what we had done.
"At 3-1 down we thought it wasn't going to be our day and one day it will happen that Arsenal will be beaten.
"We are trying to make it last but it doesn't mean anything if you break the record but don't win anything."
Henry also paid tribute to veteran team-mate, Dennis Bergkamp.
Henry scored Arsenal's first and last goals but was first to praise Bergkamp, who
also scored one himself and set up Jose Antonio Reyes for the fourth.
The French striker said: "Thank God Dennis looked like he was 20 rather than 35. Amazing - what can you say about a guy like that?"
Bergkamp, though, was quick to pass on the praise to his team-mates.
He said: "We know Middlesbrough are a difficult team to play against and at 3-1 down what are the chances to come back?
"But we showed some good spirit. We got the early second goal and we kept on going.
"There is a lot of talent in the team and it showed and in the end I think we deserved it."
