The summer transfer window has now begun, with rumours and speculation continuing to swirl as Liverpool eye possible reinforcements.

Jurgen Klopp's champions have not been particularly busy during recent windows, but that has not stopped the rumour mill from linking them with additions.

Here, Sports Mole rounds up the latest news on possible comings and goings from Anfield.

Wednesday morning's Liverpool transfer talk news roundup:

Sheffield United 'include £40m buy-back clause in Rhian Brewster bid'

Sheffield United have reportedly made progress with their bid to sign Liverpool forward Rhian Brewster.

While a number of clubs are interested in the England Under-21 international, few are prepared to consider including a buy-back clause which could benefit Liverpool in the future.

That stance has allegedly led to the likes of Crystal Palace and Brighton & Hove Albion now only being regarded as outsiders for the youngster.

According to The Sun, Sheffield United are prepared to pay £17m for Brewster, as well as giving Liverpool the option to re-sign their academy graduate for £40m at a later date.

The Blades have been forced to act after failing to find the back of the net in Premier League fixtures against Wolverhampton Wanderers, Aston Villa and Leeds United respectively.

One potential stumbling block is Brewster's desire to return to London, where he lived until 2015 before leaving Chelsea for Merseyside.

Liverpool 'allow Sheffield United to talk to Rhian Brewster'

Sheffield United have reportedly made progress in their bid to sign Liverpool striker Rhian Brewster.

The arrival of Diogo Jota from Wolverhampton Wanderers has led to the Premier League champions being prepared to cash in on the England Under-21 international.

Despite the youngster preferring to return to London, Sheffield United are regarded as the favourites to win the race for the 20-year-old.

According to the Daily Mail, Liverpool have allowed Brewster to hold discussions with the Blades, who are prepared to meet their transfer demands.

As well as receiving in excess of £17m for Brewster, Liverpool are insisting on a buy-back clause being included in any deal.

As it stands, other interested clubs such as Crystal Palace and Brighton & Hove Albion do not want to insert that option in the paperwork.
