Arsenal midfielder Ainsley Maitland-Niles has joined Southampton on loan for the rest of the season.

The 25-year-old, who also plays in defence, spent the second half of last season on loan at Roma.

"Ainsley is at a good point in his career, with a lot of experience already," Saints manager Ralph Hasenhuttl said.

"But he is also still a player with potential and he is someone who can definitely help us.

"I think he fits well with us and can develop his game even further during his time here.

"He can also play in different positions, which is always a good thing. I am pleased to welcome him as part of our squad."
