There's a number of out-of-contract stars looking to be snapped up before the season gets into its full stride, who could prove to be bargain signings. Here's a look at some of the best free agents who Leeds United and their Premier League rivals could look to snap up in the near future.
1. Danny Welbeck
The former Arsenal and Man Utd striker has just been released by Watford. He's not been at his best for some time now, but could yet recapture the form that saw him make England's last World Cup squad. Photo: MATT DUNHAM
2. Jack Wilshere
Another former England star looking for a route back to the big time, Wilshere is on the hunt for a new club after being let go by West Ham. He's still only 28, but has seen his career hampered by injury thus far. Photo: Stephen Pond
3. Fabio Borini
A bit of a left-field one here, but the ex-Liverpool man could still prove a useful rotation option. The 29-year-old has just left Serie A side Verona, following a spell with AC Milan. Photo: Alessandro Sabattini
4. Shinji Kagawa
He may well look to end his career in Japan, but the 31-year-old could potentially pursue one more big challenge and return to the Premier League for the first time since leaving Man Utd in 2014. Photo: Toru Hanai
5. Mario Mandzukic
The 34-year-old is likely to demand a hefty wage, but his experience could prove invaluable. The 2018 World Cup finalist has won league titles with Bayern Munich and Juventus in the past. Photo: ISABELLA BONOTTO
6. Steven Defour
The 32-year-old is another experienced player who could be a fine rotation option. He's won league titles in his native Belgium before, and picked up over 50 caps before retiring from international football. Photo: JASPER JACOBS
