Manchester United must pay another £1.2million to keep Henrik Larsson for the rest of the season, reports today suggest.

The former Celtic and Barcelona ace joined United on January 1st in a loan deal until March 12th from Swedish club Helsingborgs.

And he promptly endeared himself to the Old Trafford faithful by playing a starring role in Sunday's FA Cup third-round win over Aston Villa.

Larsson netted in that victory to cap a fine display, and now there are reports that his loan deal could be extended to the end of the season.

But, according to a report in The Sun, that would cost United another £1.2million, with Helsingborgs looking for hefty compensation.

Helsingborgs chairman Sten-Inge Fredin said: "The exact sum a deal like this will cost United depends on a lot of circumstances. For example, we would have to decide if we need to replace him in our own team.

"It is, first and foremost, up to Henrik if he will stay in Manchester. If he wants that, then we are certainly up for discussions with United."
