Zlatan Ibrahimovic has undergone successful surgery on the knee injury that ended his season, Sky Sports reports.

The forward sustained "significant knee ligament damage" during Manchester United's 2-1 Europa League win over Anderlecht in April and was subsequently ruled out for the remainder of the campaign.

Mino Raiola, Ibrahimovic's agent, also revealed in a statement detailing the surgery that the 35-year-old had not suffered a "career-ending injury."

Ibrahimovic, whose present deal at United expires in the summer, underwent surgery at the University of Pittsburgh Medical Center and has already begun his rehabilitation programme in the United States.

"Zlatan Ibrahimovic has undergone successful knee surgery. He will make a full recovery and has not suffered a career-ending injury," a statement from Raiola read.

"The procedure was performed by Freddie Fu, M.D, and Volker Musahl, M.D, of the UPMC Sports Medicine program in Pittsburgh.

"Zlatan has started rehabilitation at UPMC and will remain under the care of Dr. Fu and Dr. Musahl throughout his recovery.

Ibrahimovic vowed to come back stronger from the injury and insisted that "giving up is not an option", despite manager Jose Mourinho voicing his fears that the Swede's recovery will be "really, really hard" given his age.

The former Barcelona and AC Milan player joined United last summer after leaving Paris Saint-Germain and scored 28 goals in 46 appearances during his debut season in England.
