The 22-year-old joins Ralph Hasenhuttl’s side after three years at St Andrew’s, where he scored 38 goals in 123 appearances with Hasenhuttl confirming he has been “monitoring Adams for some time” and that he “fits the profile” of a player Southampton needs.
Leicester-born Adams, who has played for the England Under-20s, started his senior career at non-league Oadby Town before moving to Ilkeston Town, he then went on to get his break with a move to Sheffield United in 2014.
Since then the forward has kicked on, and enjoyed a stellar season in the Championship in the last campaign, notching 22 goals for the Blues.
So, will Adams prove a good signing for Southampton?
“Che Adams for £16million, in my opinion, is a fantastic piece of business.
“As a Palace fan, I’m looking with envy at Southampton as they’re getting a top player who’s only going to improve and will have a meaty resale value.
“With 22 goals in the Championship last year it would be impressive if he could get to around halfway.
“Adams provides much more than just goals though, that pace and aggression as the first line of defence will really suit Southampton and Hassenhuttl’s style of football – and it might mean Southampton stop playing Shane Long.”
“This is a seriously good signing and a seriously good deal for Southampton.
“He is the sort of striker who the St. Mary’s faithful will adore. Hardworking, pacy and lethal in front of goal.
“£15million may look like quite a lot now but it will only take him scoring around ten goals next season for that to start rocketing up and I think he will manage that with ease.
“I am pretty surprised that there was not more Prem interest to drive the fee even higher but that is all to Southampton’s gain.”
“This is excellent business for Southampton, and I think that the fee splashed out for Adams is a little bit of a bargain.
“Adams is a young forward with his best years ahead of him, and he heads to the Premier League full of confidence after smashing home 20+ goals in an average Birmingham side.
“He’s robust with his play and can deal with all kinds of defenders, which will be a useful attribute to have heading into the Premier League.
“Southampton have a real talent on their hands now, and if they manage him correctly, Adams will be a big hit down on the South Coast.”
“Incredible signing, and just the right sort of club for him as well.
“The fee looks big but Premier League sides can spend those figures now without fear of getting into debt. Adams was outstanding for Birmingham last season, the third player in 40 odd years to get 20 league goals for them.
“He plays with a rawness I like, he’s alert and can finish but he has a certain power and aggression that comes from fighting his way through the divisions.
“He needs regular game time, there isn’t a doubt about that, but I think he’ll be tremendous for the Saints. They’ll afford him the time to settle and I firmly believe they’ll be rewarded.”
