Football
Anthony Martial has the attributes to be among Manchester United's best-ever strikers, says clubmate Daley Blind.
"He is a big talent, he is still young and we cannot forget that. But you can see on the training pitch and even in the matches already how much quality he has," Blind told the club's website.
"He is very quick of course, he is strong and I think he is really calm in front of the goal. He has everything needed to become a great striker."

A reminder that this year's Superbowl between the Denver Broncos and the Carolina Panthers takes place on 7 February, and there will be live video and text coverage right here on the BBC Sport website.

'The atmosphere was electric'
Football
Interviewing footballers is not always the easiest thing, and it is not helped when the team are in a party mood after securing their place in a Wembley final.
Liverpool midfielder Joe Allen spoke to BBC Radio 5 live minutes after his side’s Capital One Cup semi-final penalty shoot-out victory over Stoke City. His interview competed with chants from exuberant team-mates in the background singing a popular song about Kolo and Yaya Toure.
The Welshman, who scored the winning penalty, said: "Sometimes it's more exciting to get through like this. It's not good for the stress, but the atmosphere afterwards was electric".
The Reds won 6-5 on penalties and will play Manchester City or Everton at Wembley on 28 February.
'We were by far the better team'
Football
Stoke manager Mark Hughes, unsurprisingly, disagreed with Klopp's assessment that Liverpool deserved to progress.
"I thought we were by far the better team," he said. "We were behind in the tie and I'm proud of what the players produced.
"Nobody gave us a chance - why they would do that I don't know. We've proved for a couple of years that we're a good team. I think Liverpool were delighted to go to penalties and then it's a lottery.
"We got a win on paper - goodness knows how long it's been since we won here - but the objective was to get to a Wembley final which we didn't."
