The 26-year-old and Southampton-born forward completes the switch ahead of a reported £20-million permanent move at the end of the season.
“We have admired him for some time now, not only for his ability, but also his character and personality, which we feel will be an ideal fit in our dressing room,” said Southampton manager Mark Hughes to the club’s official website. “He’s obviously a local boy, who gives us another excellent option up front.”
Ings, who has had an unfortunate knack for picking up long-term injuries, made just 25 appearances for Liverpool since 2015 scoring four goals. He had to twice battle back from serious knee injuries whilst with the Reds.
“He didn’t get to play as much as he would have liked at Liverpool, but he has been injury-free for some time now and has a real point to prove,” said Hughes. “It’s a great boost for us on the eve of the season to bring another quality player into the squad, and we’re excited about what he can bring to the group.”
Ings joined Burnley from Bournemouth in 2011 where he made 130 appearances and scored 43 goals for the Clarets, which garnered attention and an eventual move to Anfield.
“There was significant competition for Danny, with a lot of clubs keen to complete a deal for him,” began Hughes, “so we’re clearly delighted that he chose to join us.”
