Arsenal deny Paul Clement his first win at the Liberty stadium with impressive display.
Swansea gave a good account of themselves in the first 30 minutes before Giroud scored in the 37th minute.
From then on, it became a one-way traffic for the gunners. In the 54th and 67th minutes, Jack Cork and Kyle Naughton both scored an own goal to give Arsenal a three-goal lead before Sanchez capped up a very commanding display by gunners in the 73rd minute.
Giroud have now scored 5 in 5 starts for the gunners. Though Arsenal won convincingly, the attitude of Sanchez will be a worry for Wenger and Arsenal fans.
When he was substituted in 79 minute, he threw his gloves away and nearly hit the water bottles and also against BOURNEMOUTH he was seen throwing tantrums. Sanchez was angry for been substituted but for a game that is done and dusted, it really childish for a player of his calibre.
