Better play from both teams. Kind of. Arsenal midfielder Aaron Ramsey gives the ball away to Gareth Bale, who steams down the left side and lays a nice little centering pass to Rafael van der Vaart. It's a little bit too far behind the Dutch midfielder, however, and he can only blaze a shot high over Wojciech Szczesny's goal.
Minutes later Ramsey makes up for his (latest) mistake by playing a sublime through ball to Robin van Persie, who's behind the Tottenham Hotspur defensive lines in the left channel. Younes Kaboul eventually gets over to
tackle foul him, and fortunately for Spurs its a) outside the area, just and b) Mikel Arteta decides to spank it out of play for no apparent reason. So it's still 0-0.
So I guess that's not better play so much as more mistakes by both sides. And now Tottenham right back Kyle Walker is down after a clash of heads with van Persie, who was... heading the ball completely legally. Get up, kid.
