Arsenal boss Mikel Arteta has explained their loan departures of Albert Sambi Lokonga and Marquinhos.

Belgian midfielder Lokonga has joined Crystal Palace, while Marquinhos is now with Norwich City.

Arteta said today: "It was a really tricky one, but in the end really positive. We had three key areas we wanted to improve, and got players at a great level.

"Sambi [Albert Sambi Lokonga] needs time to develop, and we have found the right club.

"Marquinhos, it will be a really good test for him, and Cedric was demanding minutes. It was difficult to let him go but we have to respect his wishes to play."
