Alex Oxlade-Chamberlain scored two goals as Arsenal booked their spot in the quarter-finals of the EFL Cup with a 2-0 win over Reading.
The Championship side went into the match looking for their first ever win over the Gunners, but it was an easy win for Arsenal in the end, thanks to a double by the Ox, who seemed to be overcoming his difficult start to the season.
The brace takes his tally to five for the season – which is his best return in a season for the Gunners.
Except for Elneny and Iwobi who kept their places, Arsenal fielded a new team, including Lucas Perez, who came off the bench against Boro at the weekend.
Olivier Giroud made his return to the first-team fold as a second half substitute.
Arsenal have not won the League Cup since 1993.
Liverpool are also through to the fifth round courtesy of a brace from another England striker, Daniel Sturridge as they defeated Tottenham 2-1.
The striker opened the scoring early at Anfield after exploiting a Spurs mistake. He doubled the lead in the 60th minute
Liverpool were forced to endure a nervy end to the evening, however, as Vincent Janssen pulled one back for Tottenham with his penalty after Lucas Leiva fouled Erik Lamela in the area.
