Lambert undergoes Liverpool medical
Lambert, 32, confirmed on Saturday that he has had his medical with the Reds ahead of the switch, which is going to cost the Premier League runners-up four million pounds plus add-ons.
"The medical went well," Lambert told Sky Sports News at Liverpool John Lennon Airport. "I'll speak properly about it, hopefully, very shortly. It's been a crazy football year to be honest, the way it's carrying on."
Asked whether he had spoken to Steven Gerrard about the move while on England duty, he said: "I've spoken to Stevie a while ago, but I'll speak properly on Monday."
The striker is expected to provide back-up for first-choice strikers Luis Suarez and Daniel Sturridge as Liverpool prepare for Champions League football next season on top of their domestic requirements.
He suggested it would be hard to leave St Mary's after enjoying so much success with the club.
He said: "There's lots of emotions as you can imagine so it's something I need to address and obviously I will address all parties when I get the chance."
Lambert was an unused substitute for England in their 3-0 World Cup warm-up victory over Peru at Wembley.
