Arsenal manager Mikel Arteta says Raheem Sterling has a point to prove following his loan arrival from Chelsea.
The 29-year-old forward completed a shock deadline-day switch after being deemed surplus to requirements by Blues boss Enzo Maresca.
Sterling could now make his debut for Arsenal in Sunday's north London derby at Tottenham, having been reunited with Arteta who coached him during his time at Manchester City.
"He looks great," said the Gunners boss of Sterling. "First of all because he has a big smile on his face, a lot of energy. He's at it and he wants to prove a point.
