Is Kemar Roofe worth £3 million to Leeds United?

Antonsson is to undergo a medical and discuss personal terms with Leeds after United agreed a fee with his current club Kalmar. His move from Sweden is likely to be sealed before the end of the week.

The 25-year-old has drawn interest from the Championship by establishing himself as the leading scorer in Sweden’s top flight with 10 goals in 12 games for Kalmar and United are working to make him their first summer signing.

Leeds want to sharpen their attacking edge next season and Antonsson – a player who worked with new United assistant Pep Clotet at Halmstads in 2011 – is one of several strikers on their radar.

The Elland Road club are increasingly hopeful of persuading young Manchester United forward Ashley Fletcher to quit Old Trafford for West Yorkshire when his contract expires at the end of this month, a move which would cost Leeds a fee in compensation.

United have also shown a keen interest in League Two player-of-the-year Roofe but sources at Elland Road say the club see Oxford’s valuation of him as excessive.

Oxford are believed to be asking in the region of £3m for a 23-year-old who finished the 2015-16 season with 26 goals and nine assists.

Roofe is 12 months into a three-year contract at the Kassam Stadium and Oxford will be forced to pay a large percentage of any fee to his former club, West Bromwich Albion, through a sell-on clause.

United, meanwhile, are turning their attention to other centre-backs after Bournemouth’s Tommy Elphick sealed a move to Aston Villa.

Leeds were one of several Championship sides keen on taking Elphick from Dean Court but the experienced defender has joined Villa in a £3m deal after passing a medical yesterday.
