Damola Ajayi played for Tottenham in last season's Europa League
Doncaster Rovers thrashed Championship Middlesbrough to send them out of the Carabao Cup and inflict a first defeat on Rob Edwards as head coach.
Two early first-half goals and a double late in the second half helped last season's League Two champions easily book their place in round two.
Edwards had retained six players from the side that beat Swansea on the opening day of the season in an effort to keep some of that momentum but it was Doncaster who played with far more confidence despite changing their entire starting 11.
Rovers, who have two wins from two in League One, needed just over 10 minutes to break the deadlock as a fine lay-off from veteran forward Billy Sharp allowed Ben Close to score with the aid of a deflection.
Delano Burgzorg hit the post from a narrow angle for the hosts, but Grant McCann's team went two up midway through the first half.
Jordan Gibson's cross reached Tottenham loanee Damola Ajayi and, although his took a final touch off new Boro defender Alfie Jones, it was credited as a first senior goal for the 19-year-old winger.
Ian Lawlor made saves to stop Burgzorg and Morgan Whittaker from reducing the deficit but a comeback never really looked likely.
And it got much worse as Robbie Gotts' first goal since joining from Barrow in the summer and a fourth in injury time from Tom Nixon ensured the Teessiders' exit from the competition at this stage for the first time in three years.
Edwards: Doncaster defeat 'not acceptable'
McCann: 'The performance was top class'
