Arsenal boss Unai Emery insists he's happy to stick with Granit Xhaka in his starting line-up.
Emery's backing of Xhaka ahead of Lucas Torreira has been questioned.
However, after victory at Cardiff City, Emery said of Torreira: "He's improving and getting to know his teammates. For me, all the minutes he's playing are very important for the performance. [He needs] to continue working.
"Every minute they are playing, they are [improving] their performances. It's very important also for me to have another [option] in midfield. Matteo has started very well in the Premier League. Xhaka is very important for us and Elneny is working well every day. We need good players and good commitment when they are on the pitch. Lucas is like that."
