The third round of the Capital One Cup for 2014/15 was completed on Wednesday night with four more Premier League clubs progressing to the final 16.
Reigning league cup champions Manchester City produced a stunning second-half performance to hammer Sheffield Wednesday 7-0 at the Etihad Stadium.
Veteran midfielder Frank Lampard opened the scoring early in the second half for his second goal in two outings for his loan club before Edin Dzeko added a second in the 53rd minute.
City then really piled it on with Jesus Navas grabbing a third a minute later and Yaya Toure converting a penalty on the hour-mark after Kamil Zayatte was sent off.
Dzeko scored his second in the 77th minute prior to Jose Angel Pozo grabbing his very first senior goal for City which preceded Lampard's second on the night to ensure that Manuel Pellegrini's side moved through to the fourth round.
Chelsea followed City into the next phase by edging Bolton 2-1 at Stamford Bridge courtesy of a 55th-minute, 25-yard strike from Oscar, setting up a meeting with League Two club Shrewsbury Town.
Jose Mourinho handed a full debut to young French defender Kurt Zouma and it proved a masterstroke as the teenager fired home a Loic Remy header after a corner to give the Blues the lead in the 25th minute.
Bolton responded six minutes later when Matt Mills headed home Liam Feeney's set piece but Chelsea ended up in front at the final whistle thanks to Oscar's match-winning effort.
Elsewhere, Brighton & Hove Albion were too good for Burton Albion with a 3-0 away win while Tottenham came from behind with three goals in 20 minutes to overcome Nottingham Forest 3-1 at home.
West Bromwich Albion needed two very late goals from Gareth McAuley and Saido Berahino to edge top flight rivals Hull City 3-2 at The Hawthorns and ten-man Newcastle United required extra-time to beat Crystal Palace 3-2 after summer signing Emmanuel Riviere netted a double and Paul Dummett headed home the winner during the additional 30 minutes.
