Gary Neville has claimed that Manchester United are not "killers in the final third" and believes that Jose Mourinho is yet to mould his players into a team.

The Red Devils fell to a shock 1-0 defeat at Newcastle United on Sunday, leaving them 16 points behind Premier League leaders Manchester City in the table.

United have now lost five games in the Premier League this term, equalling their tally for the whole of last season, and Neville believes that his former side are not playing to their full potential.

"The individual talent is there but to coordinate that into a team is Jose Mourinho's job in the next few months. He has to make them into a team," the 42-year-old told Sky Sports News.

"They look like a team that play five per cent below the intensity that they can play at and should play at. That's what Jose Mourinho has to do. He has to mould this talented group of players into a team that can come together and can win the title.

"Next season will be Jose's third season and you would think in his mind, and in everyone's minds, that he has to win it next season. They have to start preparing now and days like today do damage confidence and take away the work you are trying to do.

"I still think they will finish second and they are still in the FA Cup and Champions League so there is a lot to play for, but they still have these moments where they let games drift. They missed chances, they are sloppy in the final third so many times and they have to improve that. They have to become killers in the final third and they are not at the moment."

Man United have not won the title since 2012-13, Sir Alex Ferguson's last season in charge.
