Sunderland have completed the signing of defender Adam Matthews from Celtic for a fee of £2m.
French midefielder Yacouba Sylla has spoken of his happiness and suprise at joining Aston Villa in January from Clermont.
Sylla, 22, was Villa boss Paul Lambert's first signing of the transfer window after a £2m deal from Ligue 2 French side Clermont.
The move in January came as a pleasant surprise for the French U21 International, who was only thinking about joining a Ligue 1 club at the end of the season.
'When the Premier League opportunity came, I immediately said yes.' says Sylla.
'I was absolutely not prepared for it.'
'It was impossible to refuse.'
'I was surprised they came and got me at Clermont.'
Sylla was reportedly linked with moves to QPR, Fulham, Stuttgart and Udinese, who were all interested in signing the defensive midfielder before Villa came in for him.
