The England global spent 10 years with the Gunners and, although he has been hindered by injuries at times, Pellegrini says Wilshere can still reach the heights which once saw him earmarked as a potential superstar.
Defence: Our defence was shocking during the first half at Stamford Bridge but unfortunately it was arguably our strongest back four available so Emery doesn't have much scope to improve the personnel on Saturday.
That decision came after a conversation with Emery where the new Gunners boss told him he wouldn't be a regular starter - a talk both of them have said was mutually respectful.
Arsenal will look to bounce back from a disappointing start to the new season when they welcome West Ham to the Emirates Stadium on Saturday afternoon. With two and one, it is like a 4-2-3-1 and one, two, is for a 4-1-4-1 or a 4-3-3.
"In the last two seasons he played a lot of games". They're a rock solid mid-table side.
The north London side are going through a state of transition under the new boss following Arsene Wenger's decision to step down after 22 years at the helm.
"There are three points on this game". The Hammers have won just one of their past ten away games at fellow London teams in the Premier League and that sole success came at Crystal Palace back on 15th October 2016.
"I'm not just playing football to play, I'm always playing football to win games and titles".
Parlour on Emery: "One thing I like about Emery, if you are not doing your job, he will take you off".
The Cottagers haven't started the season great either, losing at home to Crystal Palace before losing late on at Wembley to Tottenham last weekend.
And Owen believes they'll get their first win of the season against the Hammers, with Aubameyang likely to play a key role. But Slaviša Jokanovic's men performed with a lot of credit in the second half of that game, and even squandered a good chance when the scores were level at 1-1.
