What a Friday we have in store for you on Sportsday....

• We will be hearing from nine Premier League managers - including Jurgen Klopp and Manuel Pellegrini - ahead of a weekend of FA Cup fourth-round action 
• England cricket and Six Nations news conferences
• There is the small matter of Britain's Andy Murray in Australian Open semi-final action against Canada's Milos Raonic at 08:30 GMT
• And then Manchester United travel to Derby in the FA Cup at 19:55 GMT, a match that could decide Louis van Gaal's future

Strap yourselves in, it's going to be wilder than Storm Gertrude.
