Two topics dominated Mikel Arteta's post-match press conference on Saturday evening.
The first was Kieran Tierney's fitness following his early withdrawal against Liverpool, and the second was whether our boss could provide an update on David Luiz's knee injury ahead of Thursday's Europa League clash with Slavia Prague.
Here's what Arteta said:
on Kieran Tierney...
He felt something in his knee. He was in pain so it looks like he will be injured but we don't know how long for.
on David Luiz possibly requiring surgery on his knee...
We don't know.
