Sports Mole rounds up all of the latest transfer news in the Premier League on Tuesday, August 25.
Tuesday morning's Premier League transfer talk news roundup:
Koeman took over as Barca boss last week and is expected to oversee a period of change during his first transfer window as the club look to rebuild following their Champions League humiliation at the hands of Bayern Munich.
A number of key players have been linked with moves away from the club, and Sport reports that offloading some of the higher earners remains Barcelona's first priority.
However, after that Koeman has reportedly targeted a new central defender, a new left-back and a new striker.
Inter Milan striker Martinez, who has been heavily linked with a move to Camp Nou for a number of months now, would be the most expensive of those with Barca hopeful of striking a deal worth €65m (£58.7m) with players included on top of that.
Manchester City's Eric Garcia, who came through the ranks at Barcelona's famed La Masia academy, is expected to be significantly cheaper having entered the final year of his contract at the Etihad Stadium and already indicated that he will not renew.
Koeman is also thought to want Valencia's Jose Gaya, although his €50m (£45.1m) release clause could prove to be a sticking point in negotiations.
Germany international Kai Havertz is reportedly set to put pen to paper on a £130,000-a-week deal at Chelsea ahead of his proposed move from Bayer Leverkusen.
The highly-rated attacker is allegedly on the brink of completing his switch from the Bundesliga to Stamford Bridge in a deal worth up to £90m.
The 21-year-old will link up with fellow new arrivals Hakim Ziyech and Timo Werner ahead of the 2020-21 campaign, and Havertz can reportedly look forward to pocketing a lucrative salary on the blue side of London.
According to the Daily Mail, Havertz is set to agree a five-year deal worth £130,000 per week at Stamford Bridge, and his wage will go up if he meets various performance-related targets.
The Blues are also believed to be closing in on a deal for former Paris Saint-Germain captain Thiago Silva, while Leicester City left-back Ben Chilwell is supposedly inching closer towards a move to Stamford Bridge.
