Charlton Athletic have signed Conor Coventry from West Ham and Macaulay Gillesphey from Plymouth Argyle.
Both Coventry, a midfielder, and centre-half Gillesphey have been signed by Charlton for undisclosed fees.
23-year-old Coventry has signed a three-and-a-half year deal with the Addicks after making his Premier League debut for West Ham last season.
Gillesphey, 28, has joined the club on a deal that runs until 2026, with the option of adding an extra year.
"I'm delighted to bring Macaulay in," Charlton manager Michael Appleton told the club website. "He's a man mountain which helps and is left-sided, which gives us a little bit of balance.
