Manchester United's stars have jetted off on their pre-season tour of the United States as they await the arrival of imminent signing Romelu Lukaku.

Jose Mourinho's squad are on board their flight from Manchester to Los Angeles as they begin their pre-season tour across the pond.

United have named a 27-man squad for the trip but they will soon be joined by one more player - with Lukaku expected to link up with his new team-mates when he completes his world record £90million transfer from Everton.

The current members of United's squad took to Instagram to post photos of themselves on board the flight from Manchester Airport.

Juan Mata posted a photo alongside his United and Spain team-mate De Gea, accompanied with the caption: 'Beard game strong. On our way to LA.'

Ashley Young meanwhile thanked his fans for their birthday wishes, as he posted a snap with team-mates Marcus Rashford and Jesse Lingard.

Lingard himself posted a couple of additional photos to his account, with striker Anthony Martial, goalkeeper Joel Pereira and Marcus Rashford.

Rashford and Lingard, who both came through the club's youth system, are close friends off the pitch and were on holiday together in Miami earlier this summer.  

Pereira meanwhile has been included as he solidifies his spot as United's No 3 goalkeeper behind De Gea and Sergio Romero.

United's squad were earlier pictured at Manchester Airport before boarding the flight and again on the plane as they prepared for take-off. 

Mourinho has named an strong squad for the tour, including key players Pogba, De Gea, Antonio Valencia, Daley Blind and Henrikh Mkhitaryan in his travelling party.

New signing Victor Lindelof, who joined in a £30.7million deal from Benfica last month, has also been included in the squad.

Michael Carrick signed a contract extension at United in May extending his deal until 2018

The Swedish defender was pictured for the first time in United gear since being unveiled as a Red Devil, as he relaxed on board the plane with his new team.

Veteran midfielder Michael Carrick was also present after he signed a one-year contract extension at Old Trafford back in May.

Youngsters Andreas Pereira, Demetri Mitchell and Scott McTominay have made the cut as Mourinho prepares to run his rule over the club's youngsters this pre-season.

Fringe members Axel Tuanzebe and Timothy Fosu-Mensah were also pictured on board the flight, though reserve goalkeeper Sam Johnstone is back in England ahead of a proposed loan move to Championship side Aston Villa.

The Red Devils begin their pre-season with a match against Los Angeles Galaxy on July 16 before they face another MLS side Real Salt Lake on July 18.

United then take on their local rivals Manchester City in Houston before further glamour ties against Real Madrid and Barcelona, in Santa Clara and Maryland respectively.

Mourinho's squad will then fly back to Europe ahead of a clash with Norwegian side Valerenga in Oslo and finally a match against Serie A outfit Sampdoria at the Aviva Stadium in Dublin.

They are due to face Madrid once again in the European Super Cup on August 8, in the Macedonian capital of Skopje, before kicking off their Premier League season at home to West Ham on August 13.

United will hope to have Lukaku firmly bedded into the squad by then. The Everton striker is currently in Los Angeles where he completed his United medical on Saturday.

Lukaku has spent time with United midfielder Paul Pogba during his trip and the pair joked on Saturday that they would soon see each other in training, with the Belgian's move to Old Trafford edging closer to completion. 

United are pressing ahead with plans to give Lukaku a 'Hollywood' unveiling in the coming days and are not dissuaded by the striker's recent arrest by Beverly Hills police - for holding a noisy party that disturbed neighbours.

The 24-year-old is expected to join for an initial £75million deal, with £15m in potential add-ons due based on player performance.

The potential £90m fee would make Lukaku the most expensive signing ever, pipping the £89m forked out by United to re-sign Pogba from Juventus last summer.

Wayne Rooney meanwhile has moved the other way after rejoining Everton from Manchester United on a free transfer on Sunday - the 31-year-old signing a two-year deal at Goodison Park.
