Church delivers for Addicks
Simon Church scored twice on his home debut for Charlton to see off Sky Bet League Two side Oxford in the first round of the Capital One Cup.
Church, who signed a two-year deal at The Valley after being released by former club Reading, struck in each half with two clinical finishes.
Danny Green's long-range free-kick and Joe Pigott's injury-time penalty ensured a comfortable passage through to the second round for Chris Powell's men.
Despite Saturday's opening-day league defeat to newly-promoted Bournemouth, Addicks manager Powell opted to change all 10 outfield players, only one of which was enforced due to Bradley Pritchard's suspension.
Meanwhile, Oxford boss Chris Wilder rested Deane Smalley and Alfie Potter, who both bagged braces in their impressive win at Portsmouth.
The hosts took the lead after 18 minutes when Church struck from 15 yards after strike partner Pigott's goal-bound effort was deflected into his path.
Yet Oxford came back into it and James Constable tried his luck from distance, but was just off target.
The visitors' best chance fell to Ryan Williams, who was denied from close-range by Addicks goalkeeper Ben Hamer after latching on to Johnny Mullins' through-ball.
Midfielder Williams wasted another chance to level before the break when he curled over when well-placed inside the area.
Green scored after 49 minutes with a direct free-kick from 25 yards that beat the seemingly unsighted U's goalkeeper Ryan Clarke.
Church scored his second after controlling a 57th-minute pass from Cedric Evina before burying an unstoppable shot.
The hosts coasted to victory with Pigott easily converting a penalty with the last kick of the match after Jake Wright had tripped substitute Jordan Cousins.
