Mikel Arteta praised Arsenal goalkeeper Bernd Leno for repaying his faith after the German's two penalty saves clinched a 5-4 shoot-out win over Liverpool that sent the Gunners into the League Cup quarter-finals. Arteta's side had already beaten Liverpool on penalties in the Community Shield earlier this season and they repeated the trick in the fourth round tie. Joe Willock scored the winning penalty after Leno saved from Divock Origi and Harry Wilson. Adrian kept out Arsenal's third spot-kick from Mohamed Elneny, but Alexandre Lacazette, Cedric Soares, Ainsley Maitland-Niles and Nicolas Pepe all netted before Willock set up a last eight clash with Manchester City. Asked about facing City, where he worked as Pep Guardiola's assistant until December, Arteta said: "I was waiting and enjoying the victory and then we have to play Manchester City.

"It is what is. There are a lot of tough teams left in the competition." Arsenal, who haven't lifted the League Cup since 1993, have won three of their last four meetings with Liverpool in the space of just 11 weeks. Liverpool beat the Gunners 3-1 in the Premier League at Anfield on Monday, but Arsenal took the spoils against the champions in the league in July and the Community Shield in August. Arsenal's disciplined display was another sign that the FA Cup winners are heading in the right direction under Arteta's astute leadership.
