Patrick Bamford had a loan spell at Derby last season

Bamford scores against his former club

Boro joint top of the table

Shotton sent off for visitors

Miserable return to the Riverside for McClaren

Middlesbrough ended the day joint top of the Championship table after defeating previous leaders Derby County.

Ex-Derby loanee Patrick Bamford sidefooted in Adam Reach's cross after six minutes and was brought down by Ryan Shotton for a second-half penalty.

Shotton was dismissed before Grant Leadbitter converted from the spot.

Banned Boro boss Aitor Karanka watched from the stands but it made little difference to the impressive victors.

Derby, leaders at kick-off, were looking for only their second win at the Riverside this century.

But it was the hosts who made the perfect start when Chelsea starlet Bamford tucked away Reach's pass from seven yards.

It was the promising 21-year-old's sixth goal in seven games for Middlesbrough, with whom he wants to remain beyond the expiry of his loan deal in January.

Bamford, who would later depart to a standing ovation, came close to doubling the lead after collecting a Leadbitter through ball but was denied by Derby keeper Lee Grant, who completed a superb double save by palming away Jelle Vossen's rebound effort.

Jeff Hendrick wasted a rare first-half Derby chance, curling tamely at Dimitrios Konstantopoulos after a poor clearance by the Boro keeper.

McClaren made two changes at the break, with Omar Mascarell and Simon Dawkins replaced by Jordan Ibe and Leon Best.

But it failed to stifle the home side's dominance and the former Middlesbrough boss made his final change on the hour, replacing Hendrick with Will Hughes.

However, moments later things went from bad to worse for Derby when Shotton tripped Bamford in the area and saw red.

The lively Leadbitter thrashed the spot-kick low into Grant's net to put Boro, albeit temporarily, top of the Championship for the first time in two years.

They were later replaced by Bournemouth, who defeated Cardiff City 5-3.

Middlesbrough and Bournemouth have the same goal difference but the Cherries have scored more goals.

Middlesbrough manager Aitor Karanka: "I think it's the best afternoon of my career here. We played the best team in the league and are in a very good position in the table.

"It was a very good performance and I want to dedicate the victory to my staff because they are always with me.

"I could not be on the bench and they were brilliant once again."

Derby manager Steve McClaren: "Our performance was not the usual standard; it was poor. We talked all week about how organised this Middlesbrough side is.

"Normally we are around 80% in pass completion but I think today the figure will be nearer 50%.

"Credit to Middlesbrough. Once they scored the first goal, they got their tails up and deserved to win."
