Arsenal manage Arsene Wenger says to undertake two coaching roles and do them successfully is impossible.

The Frenchman speaks of the situation that new Chelsea boss Guus Hiddink finds himself in.

Hiddink is also the coach of the Russian national team and combining the roles is something Wenger says cannot be done at the highest level.

"It is impossible to take on a club and country role permanently but in the short term he can do it," he told The Guardian.

"Russia have only two minor games to deal with in the international break but long term it's not realistic. It's a special situation with Hiddink because of his close connections with [Roman] Abramovich.

"I rate Guus highly but you know with Chelsea what to expect, one super manager to leave and another to come in."
