Manchester United have signed Brazil defender Alex Telles and are closing in on a deal for Edinson Cavani as they move to strengthen their squad in the wake of Sunday's 6-1 humiliation by Tottenham.
United are understood to have agreed a fee for £13.5million plus £1.8million in potential add-ons with the Portuguese club for Telles, with a deal for free agent Cavani also believed to be close.
United have also announced the signing from Sochaux of centre-back Willy Kambwala, who will join the Under-18s squad, while Chris Smalling has completed a permanent move to Roma.
Telles told his new club's website: "To join a club with the prestige of Manchester United is a huge honour.
"You have to work hard to get to this moment in your career and now I am coming to this club, I can promise that I will give everything in my heart to be a success here."
Southampton have been in contact with Everton about re-signing Theo Walcott, after the Merseyside club landed Ben Godfrey from Norwich.
With new signing James Rodriguez having made the wide-right spot his own thanks to an excellent start to his Goodison Park career, Walcott's first-team chances look like being limited.
The 31-year-old is in the final year of his contract and while a return to Saints is thought to be his preferred choice, he has also been linked with Crystal Palace, West Ham, Fulham and Newcastle.
Norwich announced they had received a club-record fee for Godfrey, whose deal ties him to Everton until the end of June 2025.
The 22-year-old made 30 appearances for relegated Norwich in the Premier League last season, and had been linked to a number of top-flight clubs this transfer window.
The centre-back completed a medical with the Premier League leaders over the weekend before the deal was announced on Monday morning.

Tottenham have held talks with a view to signing Swansea centre-back Joe Rodon, while Ryan Sessegnon has joined Bundesliga outfit Hoffenheim on loan for the rest of the season.
The 20-year-old has struggled to make an impact since joining Spurs for £25million last summer and has been sent out to get some game-time.
