New boys Lewis Baker and Ashley Fletcher scored their first Middlesbrough goals in a comfortable 3-0 Carabao Cup win over Scunthorpe.
Baker, on loan from Chelsea, and Fletcher, signed from West Ham for B£6.5million, have had few chances to impress since moving to the Riverside this summer.
But the pair were lively throughout as their goals, combined with former Manchester United full-back Fabio's maiden effort for the club, secured Middlesbrough's progress.
The game began in end-to-end fashion until the hosts' extra quality told in the 17th minute.
Adama Traore capped a lively start by jinking his way down the right wing and sending in a pinpoint chipped cross, with an unmarked Fabio belying his diminutive stature to nod home.
