THE deal to bring Carlos Tevez to Old Trafford is "over-complicated" according to Man United chief David Gill.

Tevez will fly to Manchester for a medical which should mark the end game in a £30million move from West Ham.

However, with the Premier League insisting any deal must be done directly between United and the Hammers - rather than Kia Joorabchian, who owns Tevez's economic rights - the saga is set to rumble on yet.

Red Devils' legal expert Maurice Watkins has remained in England as efforts to resolve the dispute intensify.

And, after landing in Tokyo with the United party at the start of the club's four-match Far East tour, Gill confirmed United's intention to make Tevez their player.

"We are working on it," he said.

"In my opinion, it has become over-complicated. Effectively, we are trying to work with four parties; the player, West Ham, the company who own Carlos' economic rights and the Premier League, in order to sort it out.

"The player will have a medical at some point this week, then we will take it from there.

"We still have to sort out the paperwork, but we are confident that can be achieved in the course of the next week or so."

Even if Tevez manages to complete his move this week, he is not likely to join his new team-mates until they return ahead of the August 1 friendly with Inter Milan at Old Trafford.

Another absentee from the trip is South Korean midfielder Park Ji-sung, who will possibly be out of action until January after a knee operation.

Park will make a public appearance when United land in Seoul on Wednesday but Sir Alex Ferguson confirmed the 26-year-old former PSV Eindhoven star will be restricted to a watching brief for quite a while after undergoing surgery last April.

"He won't be available until December or January," said Ferguson.

"It is very disappointing but hopefully we have the squad to cover injuries this year."

Of United's other injury absences, Ferguson reported both skipper Gary Neville and veteran front-man Ole Gunnar Solskjaer should be back in training ahead of the season-opener against Reading on August 12.

Louis Saha will be out slightly longer, Fergie confirming it would be mid-August before he will be back training.

However, it appears Gabriel Heinze has played his last game for the club.

The full-back has expressed a desire to leave Old Trafford, with arch rivals Liverpool showing an interest.

Ferguson seems resigned to his exit.

"Gaby's agent has advised us that he wants to move on," he said.

"I am not too sure about that and we do not have a concrete offer from any particular club.

"But there is some momentum regarding the player's next move, even if nothing is close at this moment in time."

Both Tevez and Heinze played in Argentina's 3-0 Copa America defeat to Brazil last night.
