Chelsea were 5-1 winners at Charlton in the FA Cup
Arsenal won 4-1 at Portsmouth on Sunday
Recommended bet: Chelsea draw no bet
London rivals Chelsea and Arsenal meet at Stamford Bridge in a box-office Carabao Cup semi-final first leg on Wednesday, made even more intriguing by a change of leadership at the Blues.
Liam Rosenior is in the technical area at the Bridge for the first time looking to outwit opposite number Mikel Arteta in a game that promises to be tight.
Team news
New Chelsea boss Rosenior will leave it late to decide whether Reece James, Malo Gusto and Cole Palmer are fit enough to be involved.
Moises Caicedo is suspended while Levi Colwill and Romeo Lavia remain sidelined.
Gunners' chief Arteta may well stick with Kepa in goal – as he has throughout the tournament – though he is still set to be without defenders Piero Hincapie, Riccardo Calafiori and Cristhian Mosquera.
Kai Havertz is hoping for a first start in 11 months against his former club.

Prediction
Rosenior has only been in charge at Chelsea a matter of days and has been handed quite the examination in just his second assignment, but it is one he should be trusted to pass.
It is hard to know what conclusions to draw from his first game – Saturday's FA Cup demolition of Charlton – but he has unquestionably inherited a talented dressing room which is looking for a lift.
Under previous boss Enzo Maresca’s administration, Chelsea were inconsistent, though he did oversee an excellent 1-1 draw at home to Arsenal in the Premier League, a match in which they played for an hour with 10 men.
And this could be a decent time to be playing Arsenal who, while continuing to grind out results, are not as zippy as they were earlier in the season.
And in their last performance against a Premier League opponent – last week's 0-0 draw at home to Liverpool – they were very edgy and unimpressive.
They have since come out and thumped Portsmouth 4-1 in the FA Cup but this is a gruelling part of the season and Chelsea have to fancy their chances.
At home, and with a second leg at The Emirates to come, they could do with an advantage.
