N'Diaye signing 'lifts' Sunderland

Sunderland manager Martin O'Neill says the capture of midfielder Alfred N'Diaye has given the club "a lift".

The Black Cats boss says the French Under-21 international, who has signed at the Stadium of Light on a three-and-a-half-year contract, is keen to "prove a point" and perform well in the Premier League.

Sunderland are 14th in the Premier League, six points above the relegation zone.
