Things change in the blink of an eye in football. The Football Whispers Index takes the latest transfer rumours and gives them a score out of five; the higher the score, the more realistic and reliable the Whisper.
Here are today's top five emerging whispers. And keep an eye on Transfer Talk for all the latest gossip.
Malcom to Everton
Bordeaux chairman Stephane Martin will reportedly meet representatives from Everton to discuss the transfer of the Brazilian attacker. Marco Silva's side have prepared a £30 million plus add-ons deal for the 21-year-old, to whom they will offer a five-year deal on £80,000-per-week, according to Sky Sports. Malcom was linked with a transfer to England midway through last season but Bordeaux held firm. However, the Ligue 1 side appear open to a sale this summer.
Yerry Mina to Boca Juniors
Barcelona's Colombian centre back is seeking first-team football following half a season on the fringes at Camp Nou. El Mundo Deportivo report that Boca Juniors are offering a way out for the towering defender who is behind Gerard Pique, Samuel Umtiti, and new signing Clement Lenglet in the pecking order. Boca reportedly have offered £4.5m in loan fees, and included a clause of £9m to make the transfer permanent further down the line.
Diego Laxalt to Bournemouth
Bournemouth are due to make a move for the Genoa midfielder who shone at left-back for Uruguay during the World Cup, according to the Sun, who believe the transfer fee will be in the region of £25m. The 25-year-old could also do a job in midfield and Eddie Howe is looking to make Laxalt the club's second summer signing after the acquisition of promising midfielder David Brooks from Sheffield United.
Marko Arnautovic to Manchester United
West Ham have spent big in the transfer market this summer, but the next piece of business involving the east London club could involve a player on his way out. Arnautovic has been deemed surplus to requirements after a number of high profile signings in this transfer window. According to Talksport, Manchester United could be the side to offer the Austrian a deal.
Petr Cech to Chelsea
With Thibaut Courtois seemingly set to join Real Madrid, Chelsea are setting their sights on two goalkeepers who already ply their trade in the Premier League. Former stopper Cech could be set for a return to the club as reported by Sky Sports, with Leicester's Kasper Schmeichel also in their sights. New Blues boss Maurizio Sarri is keen to assemble a settled side as soon as possible, so is already preparing for Courtois' departure.
