In addition to the Champions League draw, there are nine Premier League news conferences.

First up at 09:00 GMT is Arsene Wenger on the eve of his 1,000th game in charge of Arsenal. Since his appointment on 30 September, 1996, 153 managers, caretakers or management teams have taken charge of Premier League clubs and 18 years on, the average stay of a top-flight boss stands at 1.86 seasons.

The retirement of Sir Alex Ferguson left Wenger as English football's longest-serving manager and, of the 19 others in the Premier League when he arrived, only Harry Redknapp remains a club boss.

No team in this season's competition makes more tackles than Atletico, who average 24.5 per game. But the lack of experience is a concern, even if they have 32-year-old Spain striker David Villa in the ranks. Diego Simeone already looks like an outstanding coach, but the Champions League last eight - especially such a strong line-up as this - is a step into the unknown in his managerial career.

The Champions League quarter-final draw tops the Sportsday Live agenda. The great and the good of European football are gathering in Nyon, Switzerland to discover who they will face in the last eight.

The draw is due to begin at 11:00 GMT.

A reminder of the teams still in the competition: Manchester United (7th in the Premier League), Chelsea (1st in the Premier League), Real Madrid (1st in in La Liga), Atletico Madrid (2nd in La Liga), Barcelona (3rd in La Liga), Bayern Munich (1st in Bundesliga), Borussia Dortmund (2nd in Bundesliga), Paris St-Germain (1st in Ligue 1).

A Europa League match was halted for 12 minutes after travelling Basel fans threw objects at Salzburg players. Basel were trailing 1-0 on the night and on aggregate when the two teams were led off in the 30th minute.

Basel captain Marco Streller and club president Bernhard Heusler both appealed to their fans for calm before the game continued. The Swiss side, down to 10 men for most of the match, made it through to the last eight with a 2-1 aggregate win.

British number one Andy Murray says he will find it "very hard" to find a new coach who is as talented as Ivan Lendl. The defending Wimbledon champion and his Czech mentor announced their mutual decision on Wednesday to end their partnership after more than two years.

"Ivan's a very hard person to replace," adds Murray. "You don't replace his sort of experience easily." Under eight-time Grand Slam champion Lendl, Murray won the 2012 US Open, an Olympic gold and Wimbledon last year.

Tottenham manager Tim Sherwood says the manner of his team's display in their narrow Europa League aggregate loss to Benfica shows he has his players' support. Despite losing 5-3 on aggregate, Spurs drew 2-2 in Lisbon.

Sherwood accused his team of 'lacking guts' after they were thumped 4-0 by Chelsea on 8 March. But the Spurs boss adds: "It's evident the players are on my side. My little rant has done them no harm."
