Nasri joined Sevilla on a season-long loan from
Manchester City in August
Sevilla midfielder Samir Nasri is being
investigated by the Spanish Anti-Doping Agency
(AEPSAD) over treatment he received at a Los
Angeles clinic.
The Drip Doctors clinic posted a tweet saying the
on-loan Manchester City star had been given an
immunity IV drip.
It triggered a series of embarrassing tweets,
which were subsequently deleted, leading to the
Frenchman claiming his account had been
hacked.
The drip given to Nasri, 29, may break World
Anti-Doping Agency (Wada) rules.
The immunity IV drip involves one litre of
hydration and is designed to "combat superbugs
and common viruses", according to the Drip
Doctors website.
Wada place a 50ml limit on IV infusions for
active athletes in six-hour periods unless it was
"received in the course of hospital admissions,
surgical procedures or clinical investigations".
A statement from AEPSAD said it had
"commenced an investigation into treatment used
by football player Samir Nasri".
It added: "AEPSAD wants to gather all the
information and check what happened. We must
be very prudent at the moment. We can't
prejudge the player."
Former Arsenal player Nasri, who has 41 France
caps, joined Manchester City in 2011 but left in
August for a season-long loan with the Spanish
side, who are third in La Liga.
