* Chelsea's sporting director to resign at end of season
* No word from club on successor
* News follows hot on heels of Wilkins departure
Former Danish international Frank Arnesen will step down as Chelsea's sporting director at the end of the season in a second high-profile departure announced by the Premier League club in a matter of weeks.
News of Arnesen's decision not to seek a new contract once his current deal expires next year follows the club's surprise decision to dispense with Ray Wilkins as assistant manager earlier in the month.
No reason was given for the sudden exit of Carlo Ancelotti's right-hand man, which came just as last season's double-winners were experiencing their first wobble of the campaign.
Chelsea started the season in commanding form but have lost three of their last four Premier League games and now lead the standings only on goal difference from Manchester United.
Their next game is on Sunday when they travel to face Newcastle United and by then they may well have surrendered top spot, with United and Arsenal both with chances of replacing them for at least one night.
Arnesen, who joined Chelsea as director of youth development and chief scout in 2005, took over the role of sporting director in 2009.
"The past two years I've worked more closely with the first team as sporting director and it has been a joy to work alongside Carlo Ancelotti and this exceptionally talented squad and staff," Arnesen said at www.chelseafc.com.
Chelsea gave no word on who might replace him. Spanish newspapers have reported that the club are interested in former Barcelona sporting director Txiki Begiristain.
