At the time, viewing from Block 219, I thought that Jesus was waiting for a clumsy challenge, and in doing so, allowed the Swansea defender to hook the ball clear. There was definitely some holding, but I suspected that Dean was unsighted, and would have to rely on the linesman.
I was convinced that the challenge on Sterling was a nailed-on penalty.
Now that I've seen the replays on TV, the Jesus incident is sometimes given, but often ignored, mainly because the ref is undecided.
Sterling didn't dive, but equally his touch was too heavy, which might have affected the linesman's judgement. As for contact, I've watched it a few times on a dodgy stream and still can't decide.
