Arsene Wenger believes Arsenal now have "clarity" and can regain focus after Alexis Sanchez's switch to Manchester United.

Sanchez's future had long been a hot topic, with the Chilean refusing to sign a new contract and attracting interest from both United and Manchester City.

Although a reunion with former Barcelona boss Pep Guardiola initially seemed the more likely scenario, Sanchez ended up joining United in a deal which saw Henrikh Mkhitaryan move in the opposite direction.

The transfer finally brought about a resolution to Sanchez's future and Wenger believes that will help his side, who on Wednesday overcame Chelsea 2-1 in the second leg of their EFL Cup semi-final to set up a Wembley date with City next month.

Speaking to Sky Sports after the game, Wenger said: "Uncertainty [has gone].

"We lost a great player, but of course it's true that when the team doesn't know what's going on, there's less clarity and less focus on performances.

"Now we know that we have to deal with that and we can get on by giving everyone a little bit more."
