Opposition view: Cocu feels Derby could have beaten Cobblers by even more

Derby County manager Phillip Cocu was delighted by the manner in which his side swept aside Northampton during Tuesday's FA Cup win at Pride Park.

Having laboured to a goalless draw in the original tie, the Rams demonstrated their Championship class with a dominant performance in the replay.

They won through courtesy of goals from Andre Wisdom, Duane Holmes, Jack Marriott and Wayne Rooney and will now face Manchester United in the fifth round.

“I think we played some very good football and scored four goals so I think we can be happy tonight," Cocu told Rams TV.

“There were maybe some details in the game that we can improve on, but it was a good night overall.

“We missed some opportunities to get a bigger scoreline but in general if you see how we play our football, there were great dynamics in the team with great movement and passing."

Cobblers made it 2-1 through Nicky Adams two minutes into the second-half but Marriott's header moments later effectively ended the contest, though Sam Hoskins did net a late spot-kick.

“It was a very important part of the game that we reacted when they scored the goal just after half-time," Cocu added.

“I am a little bit upset about it because we spoke at half-time to get out in the second half with a good start and take control back and not give them anything to let them back into the game.

“We didn’t start the half well, but the reaction of the team was good. We had it back under control again and it wasn’t really an issue for the rest of the match.”
