Ajdarevic was expected to report to Thorp Arch this morning and he could feature in two of United's reserve-team friendlies this week.

The League One club are interested in recruiting the Swedish midfielder, who turned 18 in April and is entering the final year of his contract with Liverpool's Academy.

Leeds were initially believed to be considering a loan deal for Ajdarevic but reports on Merseyside suggest he would be allowed to leave Anfield and take up a permanent deal elsewhere this summer.

United's second string tackle Darlington on Thursday and are also planning to contest a friendly against Newcastle United in Tyneside on Saturday morning, and Ajdarevic has been lined up to appear in both matches.

Gary McAllister is also maintaining his interest in Ajdarevic's Anfield team-mate Krisztian Nemeth, the highly-rated Hungarian striker who helped lead Liverpool to the FA Premier Reserve League title last season.

Nemeth is believed to be unwilling to take up United's offer of a trial at Thorp Arch, but the gifted 19-year-old is still open to a loan switch to Elland Road if McAllister pursues a deal.

The youngster scored nine times for Liverpool's second team during the 2007-08 term and appears to be edging closer to Rafael Benitez's senior squad.

He is currently involved with Hungary at the European Under-19 Championship finals in the Czech Republic and netted the only goal of the game in his country's opening group game against Bulgaria yesterday.

It was Nemeth's six goal in the competition overall and makes him the leading scorer alongside Michalis Pavlis of Greece.

Ajdarevic is one of a number of trialists who have already linked up with Leeds for the early stages of the English pre-season.

Young striker Marcus Haber – available on a free transfer from Dutch club FC Groningen – has travelled with McAllister's first team for their tour of Eire, and Haber's Canadian compatriot Josh Wagenaar has followed him to Yorkshire this week.

Wagenaar is a free agent after cutting short his contract with Den Haag in January.

He won his first senior cap with Canada's national squad during an Olympic qualifier against Mexico in March and will train alongside Ajdarevic and United's reserve pool this week.

Wagenaar was previously linked with a move to Toronto FC, who are coached by former Leeds caretaker John Carver.

Meanwhile, United striker Tomi Ameobi is set to embark on a trial with Doncaster Rovers.

Ameobi, who is also interesting Scunthorpe United, has been offered a new one-year deal by Leeds but may opt to move away from Elland Road in search of first-team football.

The 19-year-old academy product would command a fee as a result of his age.

Meanwhile, Stoke are close to making Liverpool goalkeeper Scott Carson their first summer signing.

The clubs are said to have agreed a fee for the England international of around £4m.

The 22-year-old who started his career at Leeds United spent the whole of last season on loan at Aston Villa, who were were put off by a reported £10million price tag.
