The more I've thought about it the more impressed with Walker I am. He had a real determination about him too, which is important at a time like this. Much like Sterling, when he has the confidence to stamp his authority on proceedings he becomes a truly top class talent.
There were a few casual moments early on where he could have done better, similar to De Bruyne. But he did iron it out eventually.
One thing I noticed was how often he came inside, particularly in the first half. I do think he got a bit overzealous here, I was worried at times he'd put Garcia in a sticky situation being out of position like that (although it went unpunished).
