New boy Gabriel makes his Arsenal debut this afternoon as vice captain Per Mertesacker is rested to the bench. So the Brazilian will be partnered alongside Laurent Koscielny. It is an interesting partnership as both players are supposed to be similar in style. Many have had worries that they might not be able to function alongside each other due to the past relationship between Koscielny and Vermaelen. But I tend to believe the latter just was not as good at defending as we all hoped rather than an issue of chemistry, So today's partnership looks very interesting. They have not played together in a game so we will have to hope the gel and gel fast.
