1) Arsenal can score plenty of goals
With eight goals in the last two games, it is obvious Arsenal are very comfortable in front of goal. With players like Giroud, Welbeck, Cazorla and Sanchez in the squad finding the net isnt a problem. All the Gunners need to do is be patient, play their game and the goals will definitely come.
2) Santi Cazorla is back on form
Santi Cazorla hasn't been at his best recently, but with good back-to-back performances and with two goals against Newcastle, the little magician is back and ready to show his worth. It was his 30th birthday as well. When Mesut Ozil and Theo Walcott are back, it is important for a player like Santi to be on form in order to grab those goals from midfield.
3) Set pieces are proving trouble again
Arsenal have been suffering from set pieces for as long as an Arsenal fan can remember. They seem to suffer from set pieces against any team and usually concede silly goals from them. Newcastle's goal was one of many.
4) Debuchy can play as a central defender until Laurent Koscielny is back
Debuchy had a good performance at centre-back. He was calm and showed his experience. Playing him and Mertesacker until Laurent Koscielny is back from injury is a good option for Arsene Wenger, as it brings stability to the shaky defense.
5) Support the team
When fans are anxious the players feel it. When the fans at Emirates Stadium supported the team and chanted Arsene Wenger's name at the end, we noticed how happy and relaxed they were. Support the team before, during and after the end of every game, it helps.
