The former Man United winger urges the Red Devils to support their current Manager, Ole Gunnar Solskjaer, and invest in the team heavily to compete for the Premier League next season.
With Manchester United being heavily linked with a move for Tottenham’s vice-captain, Harry Kane, Hargreaves believes that money would be better off spent elsewhere in the squad.
ahead of United’s upcoming Europa League final against Villarreal: “United could win the Europa League but the goal is to win the Premier League and the Champions League and to do that they need investment, the right recruitment, key players in certain positions.
“If you look at the squad Man City has, with the utmost respect to everyone else, that’s the best team in the country. They’ve got a coach that’s super innovative but the depth of players they have, I don’t think anyone in the country can compete.
“So for United to compete they’re going to have to invest heavily and back Ole, because Ole has got them in a position where they’re within striking distance and I think that’s good. A lot of teams sign good players but they’re not difference makers.
“I like Lindelof, I think he’s a really good player, but I think you’ve seen the impact [Ruben] Dias has had at Man City and the impact [Virgil] Van Dijk had [at Liverpool] and it might take getting one of those guys in to help Man Utd take the next step.
“It costs a lot of money but United need a centre-back, a right winger and probably a defensive midfield player.”

Pundit, Hargreaves, continued: “I’m sure everyone would love Harry Kane but that’s going to cost a lot of money, so you potentially could get two or three players for maybe one of those types of players.
“City are great examples of buying players to spread the wealth around. There’s probably six guys getting 10 goals and assists so rather than just having one guy that gets you 30 goals it might not be bad having four, five or six that can contribute and make you unpredictable.”
Manchester United will face Villarreal in Gdansk on Wednesday. With Harry Maguire sidelined for an injury, Solskjaer will seemingly be without his club captain for the Europa League final.
However, Hargreaves, who won the 2008 Champions League with United, thinks it is the best opportunity for other United players to show their promises.
“Defensively they can get tighter," said Hargreaves. "I like [Axel] Tuanzebe. I think he has the potential to be something really great but he’s had some injuries.
“I got my big break in the semi-final as a young kid against Real Madrid. So maybe someone’s going to get a big break in the final - and if you get an audition and if it goes great, that’s you set.
“If Harry can’t play it’s a huge blow but maybe this is a moment for Tuanzebe to have another one of those moments where he blows everyone away.”
