Leeds [UK], Dec 29 (ANI): Arsenal forward Pierre-Emerick Aubameyang hailed new head coach Mikel Arteta and said the team have seen a 'big difference' since his appointment."He's only been in charge for a few days, but we've seen a big difference already. We needed someone who would come in and shake the whole squad up," Goal.com quoted Aubameyang as saying."We needed someone with new ideas, with a new message and someone who would take us in a different direction. Mikel has brought all of that. We needed a fresh new start and something different and we can feel it already," he added.Arteta started his reign with a 1-1 draw away at Bournemouth on December 26, with Aubameyang scoring a second-half equaliser to secure a point.Arteta's first test at home will be the match against Chelsea at Emirates Stadium later in the day.

It's all about details with him so he talks a lot, repositions us, explains a lot of little things," Aubameyang said."He wants us to be at 200 per cent all the time, to give everything we have and leave it all on the pitch. It's exciting for us because it's so different to everything we have done and experimented with before," the striker added.Arsenal are at the 12th spot with 24 points in the Premier League standings.
