Zlatan Ibrahimovic completed his move to Manchester United on a Friday (July 1) with the flamboyant Swedish striker saying he was looking forward to a "new adventure" at the Old Trafford club.
United did not disclose any contract details but British media reported that Ibrahimovic had signed a one-year deal to join up again with the Premier League club's new manager Jose Mourinho.
United have not paid a fee to sign the 34-year-old, who was out of contract after leaving Paris St Germain.
Ibrahimovic has won titles in four different countries in a career which began with his hometown team Malmo in 1999 and has included spells at Ajax Amsterdam, Juventus, Inter Milan, where he played under Mourinho, Barcelona and AC Milan.
He has scored 392 goals in 677 games and won a trophy in each season since 2001.
Ibrahimovic retired from internationals after Sweden's Euro 2016 exit last week, having won 116 caps and scored 62 goals.
He left PSG, having made 180 appearances and netting 156 goals, after breaking the Ligue 1 club's all-time league scoring record and winning a second straight domestic treble.
