It’s that time of the year again – the transfer window is now open until September 1 and it’s sure to be a busy period as clubs look to make big signings ahead of the new season.

Here are today’s latest developments from Simon Jones and the Daily Mail Sport team…

Benfica offer for Harwood-Bellis rejected

Southampton have rejected a £17.5million offer from Benfica for defender Taylor Harwood-Bellis.

The Portuguese side, coached by Marco Silva, turned to the 24-year-old after initial interest in Chelsea’s Tosin Adarabioyo who wants to stay at Stamford Bridge.

Benfica are considering an improved offer with Harwood-Bellis interested in the move.

Eagles sign £21m right back Khalaili

Crystal Palace have completed the £21million signing of Union Saint-Gilloise full-back Anan Khalaili.

Khalaili’s move to Inter Milan fell through earlier this summer over a health issue, but he passed his medical with Palace last weekend.

The 21-year-old is being brought in to provide competition for Daniel Munoz at right wing-back.

However, there is no guarantee that the £20m-rated Colombian will stay beyond this summer amid interest from the likes of Tottenham and Everton. He has two years left on his deal.

Khalaili, who has won 16 caps for Israel, said: ‘I’m happy to be here, I’m excited, and I can’t wait to start.

‘I’ve followed the Premier League. It’s a new challenge for me, and I’ve followed Crystal Palace for a long time. I’m happy to be here.’

The 23-year-old has signed a five-year contract, becoming the club’s 10th summer signing.

Gourna-Douath said: ‘I’m really happy because it was such a long journey from the first phone call until I signed. I’m so excited to get started.

‘I’m really happy to have this experience. I got a chance to play in the Champions League, Serie A and Ligue 1.

‘I’ve learned a lot and I’m really happy to put this experience on the pitch in the Premier League. The Premier League is the dream of all footballers. Now, I have a chance to play in the Premier League, so I am excited to play.’
