LeBron James' investment in Liverpool has gone up five-fold since he first purchased a two per cent stake in the Anfield club back in April 2011, according to reports.

James paid ($6.5million) £4.8m for the stake seven years ago when his marketing firm LRMR signed a partnership with Fenway Sports Partners, who are run by Liverpool chiefs Tom Werner and John Henry.

But ESPN report that after Liverpool sealed their qualification for the Champions League final, James' investment is now worth $32m (£25m).

NBA superstar LeBron James' investment in Liverpool has gone up five-fold in seven years

The report claims Liverpool could currently be sold for £1.2billion with the Champions League final berth earning the Reds an extra £735m.

Under that measure, James' investment has skyrocketed and the Cleveland Cavaliers star could sell it off for five times what he purchased it for seven years ago.

The Liverpool venture is just one of a number of investments James, who earns a $31m salary in Cleveland, has made in recent years. The 33-year-old has also been involved with David Beckham's Miami MLS franchise.

Those investments include a tech company in Silicon Valley, a pizza start-up, his shoe deal with Nike and a partnership with Beats By Dre headphones.
