The one-cap Spanish international needs too toughen up.
Leeds United are said to be in the market for plenty of players, with a number 10 one position they hope to strengthen.
Recently Leeds coach Steve Evans even told BBC Radio Leeds that the club would like to bring in such a player to link the midfield and attack - a Matej Vydra at Reading type player:
"I think we are missing a genuine ten player. That one who can link that midfield (and attack).
"You know, not Vydra, but almost like a Matej Vydra type who can pull into those holes, pull into wide areas and suddenly create room and opportunities and who is very talented on the ball. Someone who unlocks defences."
Juanmi arrived from Malaga in the summer in a very exciting transfer, considering he had recently made his debut for the Spanish national team.
However he has struggled with the physical nature of English football during his time at St Mary's. Saints boss Ronald Koeman even told this to the club's official website last year:
“I don’t say the Premier League is stronger than the Spanish competition, but it’s different in tempo and physically what you need. That needs time.
“We speak with Juanmi about that and sometimes I am the referee if we play a game on the pitch and I don’t whistle.
“I don’t whistle because sometimes he’s falling too easy. He needs to be stronger. That we are trying to develop.
What Juanmi needs then is too toughen up, where better than in the Championship. Southampton would be giving him plenty of playing time and a crash course in the finer etiquette of English football at a fantastic football club like Leeds.
Leeds on the other hands would have a Spanish international on board to link up the play between Chris Wood and the heaps of midfield talent currently at Elland Road.
It is a deal that makes perfect sense, as long as the money is right.
