Man United are heavily linked with Juventus forward Mandzukic.
Dimitar Berbatov says Manchester United need a proven goalscorer like Mario Mandzukic.
The former United striker believes Mandzukic has the attributes to lead the line at Old Trafford.
The 20-time champions sit in 12th spot in the Premier League table following below par performances from Ole Gunnar Solskjær‘s team. Speaking to Betfair, Berbatov said: 'The winter transfer window is going to be difficult and on the pitch Manchester United aren't producing as a team at the moment. It doesn't matter how good you are, Messi or Ronaldo could go there and they would have difficulty because the team is not producing.
‘When you sell two of your main strikers you need to bring in at least one, just in case.
'Everybody can see that that Manchester United need a back up, (Anthony) Martial is injured and there isn't another really strong proven goalscorer. They have the talent in the young players but at the same time you need someone like Mandzukic.'
The Bulgarian continued: 'I think he is a really good football player and he hasn't played before in England but I hope if he comes he can straight away get into the rhythm of the Premier League.
'Ibrahimovic was 34 years old when he signed for United and he didn't have any problems. Mandzukic is a similar age and hope he could have the same impact if he signs.’
Berbatov believes United’s youngsters could learn from Mandzukic.
'I think his age is a good thing, Martial, (Marcus) Rashford and (Mason) Greenwood are all young players so they need that time and assurance that they don't need to worry and they can learn from the experience of Mandzukic.'
