LAURENT BLANC stormed out of a press conference after being asked by journalists about signing Brazil’s “least efficient striker”.
Jeffinho joined Lyon on transfer deadline day as Blanc’s turned to the January window to give their season a boost.
The French side are languishing in mid-table in Ligue 1 after an underwhelming season.
But the signing of the 23-year-old for close to £9m from Brazilian club Botafogo has been met with some criticism.
Lyon boss Blanc, who won two titles as a player with Manchester United in the early 2000s, fielded questions from journalists on the forward.
But he did not take kindly to a point on Jeffinho’s efficiency, with Opta stats suggesting he is not sharpest shooter around.
The new signing only scored two of his 55 shots for Botafogo last season and one journalist asked why Lyon opted to sign “Brazil’s least efficient striker”.
Unhappy with the question, former France manager Blanc abruptly left the press conference after a further brief exchange with reporters.
He was reportedly unimpressed with questions on the club’s transfer business rather than the upcoming game against Troyes.
It has been a difficult season for Lyon who would have been looking to improve on last season’s disappointing 8th place.
