Chelsea defender Ricardo Carvalho has written off Manchester United's chances of winning the Premiership.
United have closed the gap to leaders Chelsea to just seven points with six games remaining.
But Carvalho is confident Jose Mourinho's side will be crowned champions for the second year in succession.
'United are on a roll and doing well. But they don't have enough energy to be champions,' Carvalho told The Sun.
'Even if United beat Arsenal this Sunday the title will still be Chelsea's.
'We have a big enough advantage to win it for the second consecutive year.
'We are the best team in the Premiership and we have shown this in the last two years.
'After going out of Europe our aim now is to get the double. The league is practically in the bag and we also want the cup to show a lot of people who have criticised us that we are still the best.'
