Goals by Mikel Arteta and Alexis Sanchez have put Arsenal in cruise control against Anderlecht, the Gunners beating their Champions League opponents on Tuesday evening 2-0 at half time.
The visitors had the first concrete chance on goal nine minutes in when Dennis Praet's shot from distance deflected off Per Mertesacker and into the Gunners' side-netting.
Arsenal then threatened three minutes later when Calum Chambers picked out Aaron Ramsey, but the Welshman's effort found itself blocked by Chancel Mbemba.
The game continued to provide high-octane action when, just moments later, Anderlecht marauded into the hosts' final third once again and saw Sacha Kljestan's chance well saved by Wojciech Szczesny.
Arsenal broke the deadlock in the 25th minute when Danny Welbeck won a penalty, which Arteta duly dinked down the middle from the spot.
Just four minutes later, Arsene Wenger's charges doubled their lead, with Sanchez smashing a rebounded free kick home from the edge of the Anderlecht box.
