Wenger thinks it will heighten interest in the top flight.
“The fact that of the four top teams last year, three have changed manager will certainly create the most interest to see how they all respond to that,” the manager told Arsenal Player.
“You have less questions about Mourinho returning to Chelsea because he already knows the club and they are a stable team.
“These teams changed managers but there is a stability there [in terms of the players] so that shouldn’t create too much uncertainty.
“Pellegrini has a lot of experience, David Moyes has a lot of experience and Mourinho as well, so they will handle it very well.
“Let's not expect presents from these clubs because that would be the wrong way to go into the championship. Let's just think they will be as strong as ever and make sure that we are strong.”
