Let's talk about Keita.
The guy is just pure penetration. It's ridiculous. He was involved in the build-up play for our first and third goals plus the big chance for Salah which was saved at point blank range by Fabianski.
While he didn't get many shots off himself (in fact only one small chance from a corner, as shown above), he was attacking the box late and getting into good positions. In fact he was well positioned to score in one or two of our goals had the ball fallen elsewhere in the box.
He also created a half-chance for @GWijnaldum (also marked on the graphic) after weaving his way into the box with the ball at his feet before giving it to Gini to have the crack at goal.
Most interesting of all though was the understanding he quickly struck up with Robertson in his debut game. 30% of all passes he received came from Andy and 39% of all passes be played were in the Scots direction. Interesting stuff!
