Wenger: 'I am worried about the situation. If you want quality people in a job you need to give them a chance.
'Instability gives a chance to people who talk well and they can convince you quickly. But it is not necessarily for people who have real quality and work deeply inside the club.
'I am really concerned about that and the instability of the ownership. The consequence of that causes instability on the technical side.
'These people want to come in and buy and have quick success. They have negative results, but don't understand how difficult football is.
'I don't believe it is linked with nationality. Sam Allardyce has been sacked this week, but it could have happened to a foreign manager. A new owner comes in and wants new people, but it is all a factor of instability.'
