Barcelona striker Neymar Jr will fly to Doha, Qatar this week to discuss a potential world record $242m (€222m) transfer to Paris Saint-Germain. In England, Chelsea FC striker Diego Costa is ready to consider other options after growing frustrated at Atletico Madrid's lack of urgency, while Liverpool have joined Arsenal Football Club in the race for AS Monaco midfielder Thomas Lemar. Here's a full report of the transfer updates:

PSG set to sign Neymar

According to Mirror, Barcelona star Neymar Jr will visit Doha to meet Paris Saint-Germain chairman Nasser Al-Khelaifi ahead of what could be a world record transfer.

It is also suggested that the stopover on a return flight from a “promotional trip” to China could also include his medical before signing a deal. The Brazil international would become the world most expensive soccer player in history if French Ligue 1 club Paris Saint-Germain sign him up for a fee more than “double figure” the one Man United paid Juventus FC to resign Paul Labile Pogba last year summer. The 25-year-old has a running contract with Barcelona until the summer of 2021 that contains a $242m buy-out clause, which “ambitious” Paris Saint-Germain appear prepared to activate this week.

Diego Costa tired of Atletico Madrid's slow negotiations

Diego Costa is growing tired of Atletico Madrid's slow negotiations, and he's now willing to listen to other offers from around Europe.

According to Express, the Spain international is said to be attracting interest from Besiktas and AC Milan. Milan are searching for a new marquee striker, and he will now hear them out. Diego Costa wants to leave Chelsea this summer after being told by manager Antonio Conte that he is no longer needed at the club. However, Atletico Madrid, who're banned by FIFA from signing any new players until January 2018, are yet to make an offer for the 28-year-old striker.

Liverpool keens on luring Thomas Lemar to the EPL

Arsenal are expected to return with yet another offer, but they must now fight off competition from Liverpool as well. According to the Sun, Liverpool Football Club are now keeping close tabs on the 21-year-old as they are “fearful” their star player Philippe Coutinho may leave for Barcelona this summer.

And should this happen Liverpool Football Club will be “hunting” for a new creative central midfielder, and they've now added Thomas Lemar to their growing transfer wish list. Thomas Lemar enjoyed a superb campaign last term as he helped AS Monaco clinch the French Ligue 1 trophy.
