Manchester United defender Chris Smalling has joined Roma on a four-year deal worth 15m euros (£13.6m), rising to 20m euros (£18.1m) with add-ons.
Smalling, 30, spent last season on loan at the Italian club and helped Paulo Fonseca’s side to a fifth-place Serie A finish and Europa League qualification.
The England centre-back impressed during his stay, making 30 league appearances and scoring three goals.
United and Roma had initially struggled to reach an agreement over a fee.
The Italian transfer window officially closed at 19:00 BST but a fee was agreed prior to the deadline, allowing the deal to go through.
Manchester United earlier announced the signing of Brazil left-back Alex Telles on a four-year deal from Porto.
