Calum McFarlane: The 'tactical obsessive' who has been thrown in at the deep end at Chelsea again

Calum McFarlane will take charge of Chelsea until the end of the season after Liam Rosenior's sacking, starting with Sunday's FA Cup semi-final against Leeds.

It's not McFarlane's first stint in interim charge at Stamford Bridge.

He took temporary charge after Enzo Maresca's exit in January for Chelsea's 1-1 draw away to Manchester City and the 2-1 defeat at Fulham.

But now he faces a crucial few days as he prepares to be in the dugout for the Blues' FA Cup semi-final at Wembley before being tasked with trying to achieve European qualification.

McFarlane completed an incredible rise from grassroots football to the Premier League during his first stint as Chelsea interim boss.

The 40-year-old, who was previously serving as club's former U21 coach having joined from Southampton's academy, formed part of Rosenior's first-team staff having impressed in the hot seat.

He earned particular praise after his tactical adjustments helped claim a 1-1 draw with Manchester City at the Etihad Stadium, when Enzo Fernandez scored a dramatic equaliser.

McFarlane's success is no surprise to those who worked with him during a six-year spell as academy manager at Kinetic Academy, a London-based charity with a history of producing professional players from disadvantaged backgrounds.
