Tony Pulis gave his thoughts on Boro's 2-1 win over Rotherham United on the final day of the Championship campaign.
First half goals from Britt Assombalonga and John Obi Mikel gave Boro the upperhand, with Michael Smith halving the deficit from the spot in the second period.
“We played well first half. Again, I thought we missed a lot of chances to make it more than two. Second half we dropped off a little bit," Pulis said.
"The crowd were going up and then down and I think that affected the game a little bit, and affected us maybe.
"We’re desperately disappointed – to win five out of your last six games and not get in is a disappointment. They’ve shown good courage and commitment over that period.”
