Just generally & especially against teams that sit deep which must make up 90% of games.you obviously didn't see the heatmap from halftime they showed on the Arsenal commentary - it was like 90% up that right hand side with Hector and Theo linking up to provide the biggest threat
Both have lightening speed but average touch, vision & final ball. Feel Hector would be helped with a more rounded wide player & Walcott with a smarter fullback who can put in a cross giving the defender more to think about.
A pretty one dimensional similar duo.
