The 33-year-old will be available for a small transfer fee, but his huge wages could put off some suitors. The lack of resale value on such an old player is also a setback. However, the Sweden international is still a top-class striker, having scored 19 goals in 24 Ligue 1 appearances last season.
The three Premier League sides all suffer from a lack of depth up front, and will need to improve in the area if they are going to challenge Manchester City for the top flight title. The Citizens have made a lightning start to the season and look like the team to beat.
