Arsenal, Chelsea and Sunderland are through to the quarter-finals of the Carabao Cup, with the latter two clubs advancing after surviving a penalty shootout.
Five-time League Cup winners Chelsea defeated Southampton 4-3 on penalties, after the game finished 1-1 in regulation time. Back at St Mary's after a loan spell at Bournemouth, Shane Long was introduced as a 66th-minute sub and was successful when taking his spot-kick.
Also coming off the bench for Ralph Hasenhüttl's side was Republic of Ireland underage international Will Smallbone. Along with Theo Walcott, he missed from 12 yards as Southampton made their exit.
Thomas Tuchel's side had earlier hrough a Kai Havertz header just before the break.
But Che Adams brought the Saints level inside three minutes of the second half after Chelsea keeper Kepa Arrizabalaga failed to hold a Kyle Walker-Peters drive and the Scotland striker converted from close range.
Arrizabalaga made amends late in the game with two fine saves as Southampton piled on some late pressure but the shootout belonged to the home side.
Reece James slotted in the decisive penalty.
Arsenal eased through with second-half goals from Calum Chambers and Eddie Nketiah in a 2-0 win over struggling Leeds.
Chambers opened the scoring in the 55th minute, 23 seconds after coming on as a substitute. The defender's header looked to have been saved by Illan Meslier but goal-line technology ruled that the ball had crossed the line.
The Gunners' second came in the 69th from a poor header back by Liam Cooper which left Meslier stranded as Nketiah rounded the keeper and his mis-hit shot from a tight angle just rolled into the corner.
League One Sunderland also enjoyed a shootout win, defeating Championship Queens Park Rangers.
The North-East side won 3-1 on penalties after the game had ended 0-0.
