But the summer has been a good one so far for Arsenal as they have managed to keep some of their key players like Alexis Sanchez, Hector Bellerin and Mesut Ozil, even though the Chilean is still heavily linked with a move away.
Wenger would not say whether there had been any offers for Sanchez and said his close relationship with Paris Saint-Germain chairman Nasser Al-Khelaifi did not mean a move to the French capital was imminent. He had a scan two days ago and he's out for a while I don't know is it two weeks or one more week but he will not be available.
"Personally, I think he is a hugely talented player".
Ahead of the 2012/2013 campaign, the Dutchman - who had a year remaining on his contract at the Emirates Stadium - was sold to rivals Manchester United (much to the anger of Gunners supporters) and netted 24 goals to lead them to the Premier League title. I don't think I would have started him.
Wenger said the Chile worldwide would miss Arsenal's home fixture against Leicester City on Friday as well as the trip to Stoke City on August 19.
"He is focused. When you have treatment on the medical bench it's not easy".
'He was busy completing the transfer of Neymar.
Wenger revealed a fresh blow after confirming that Alexis Sanchez has picked up an abdominal strain and the attacker is expected to be out for at least two weeks.
For the first time since 1997, Arsenal are going into a season without Champions League football and Wenger has pledged to rest players in the Europa League. For example Ramsey, Ozil, (Per) Mertesacker, of course (Laurent) Koscielny is suspended. The club has also brought in new players like Sead Kolasinac and Alexandre Lacazette who could have a lot to offer to the success.
