Dimitar Berbatov says Manchester United players must "be f***ing better" after their debacle display towards the end of last season.
Ole Gunnar Solskjaer's Red Devils finished sixth in the 2018-19 Premier League campaign, losing out on a Champions League spot. But, they looked better when they started the new season, beating Frank Lampard's Chelsea 4-0 at Old Trafford last Sunday.
However, Berbatov hopes his former side put in a good performance through out the 2019-20 season to banish what happened last term.
"There's only one thing I'd like to see - a better performance than last season," he told the Daily Star. "The way we finished was disappointing.
"So, this season hopefully they can perform better. Not only one player but everybody as a group.
"They must say to themselves, 'OK, we need to be f***ing better'."
Berbatov, who spent four seasons at Old Trafford, said United's new signings Aaron Wan-Bissaka and Daniel James both impressed him during the pre-season tour.
"When I saw them [against Inter] in Singapore, what I saw impressed me," he said. "But friendlies are different to Premier League games.
"Sometimes you play more freely in friendlies because there's no pressure. But when the season starts, the nerves start working. Negative thinking starts - but it needs to stop."
