The Sun has reported that Southampton are among the clubs looking to secure the services of the former Arsenal forward this summer.
The 29-year-old forward wants to leave Watford this summer following the Hornets relegation to the Championship at the end of the past season.
The England international has a release clause of 5.5 million in his contract, and the Saints are reportedly looking to activate it.
Watford Spell
Welbeck joined Watford from Arsenal in the summer of 2019, but the former Manchester United forward failed to make a huge impact at Vicarage Road.
The 29-year-old made eight starts and 10 substitute appearances in the Premier League for the Hornets this past season, scoring two goals in the process, and the English forward also scored one goal in two EFL Cup ties.
