Alex Oxlade-Chamberlain has hit the crossbar twice as Swansea City and Arsenal go in goalless at half time.
The match started in real end-to-end fashion and it was Arsenal who came closest inside the opening five minutes when Alex Oxlade-Chamberlain struck the bar with a side-footed shot from just inside the box.
Swansea came into the game and worked a couple of chances; first Angel Rangel shot wide before Pablo Hernandez found Michu, who turned well but also shot just wide.
Santi Cazorla tested his range with a powerful drive from distance, but shot straight down the throat of Michel Vorm.
Both teams were passing the ball well but there was a lack of a cutting edge, summed up when Oxlade-Chamberlain miscontrolled in the box with players waiting for the pass.
A few minutes later he cracked the woodwork again, this time on his right foot from distance, but the deadlock remained unbroken at half time.
