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.
Julian Weigl to Manchester City
Borussia Dortmund midfielder Weigl is a Manchester City transfer target as Pep Guardiola looks for replacements for Fernandinho and Yaya Toure, who are both out of contract this summer. Spanish publication AS reports the Manchester club will do battle with Barcelona for the 22-year-old, who is already capped for Germany and operates primarily as a defensive midfielder.
Marcos Alonso to Barcelona
Ernesto Valverde is lining up the Chelsea left wing-back as a replacement for Jordi Alba, as he is reportedly not impressed with the full-back's performances. Lucas Digne is Barca's current back-up option in the position, but the manager is said to want improvements on his current options.
Jamie Vardy to Chelsea
The Daily Telegraph reports Antonio Conte is ready to replace Michy Batshuayi in January, and Leicester striker Vardy is one of the players on the club's wish-list. The Italian manager has been unhappy with the depth of quality within his squad since the summer transfer window closed, and will encourage the club to put this right at the earliest opportunity. Vardy heads a list which includes Christian Benteke and Richmond Boakye, but the England international would be seen as the best alternative to Alvaro Morata.
Andre Silva to Arsenal
The 21-year-old Portugal striker is one of the players the north London club will look to bring in to replace Alexis Sanchez when the Chilean leaves in 2018. According to the Daily Mirror, Arsenal will look to take advantage of AC Milan's poor start to the season, and will move for the player if the Italian giants fail to secure Champions League qualification. Despite being in and out of the side since arriving from Porto in the summer, Silva has four goals in two Europa League games this season. He also has 11 goals in his 17 caps for Portugal.
Edinson Cavani to Manchester City
Don Balon claims the unsettled Paris Saint-Germain striker has singled out Pep Guardiola's side as a preferred destination. They report the Uruguayan believes City give him the best chance of continuing his prolific goal-scoring record, but he'll first have to find a way past the club's current star strikers Gabriel Jesus and Sergio Aguero. Cavani has been unsettled since Neymar's arrival at PSG, and a move away from Paris looks increasingly likely.
