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.
Kamil Glik to Lazio
With Stefan de Vrij expected to leave Lazio and join Inter on a free transfer this summer, the Rome-based side have reportedly lined up Glik. Il Messaggero claim the Monaco centre-back has been identified by Lazio's scouting department as the perfect replacement. The 30-year-old Poland international already has experience of football in Italy, having played for Palermo, Bari and Torino between 2011 and 2016. He's expected to cost around £13 million.
Jean Michael Seri to Manchester City
Both Manchester City and Manchester United have expressed an interest in Nice midfielder Seri, according to the Manchester Evening News. Pep Guardiola and Jose Mourinho have both made a holding midfielder a priority during the summer transfer window and the Ivory Coast international's impressive performances in France have put him high on both of their wishlists. Seri was reportedly subject of a bid from Barcelona last summer, but a deal fell through at the last minute, leaving him to carry on plying his trade in Ligue 1. The 26-year-old is expected to move on when the season ends, however.
Oguzhan Ozyakup to Newcastle United
Former Arsenal youth player Ozyakup is reportedly a Newcastle United transfer target. The Turkey international had been linked with Everton, but Turkish Football are reporting that Newcastle are ready to hijack that deal. The 25-year-old is out of contract at Besiktas in the summer, and while the Super Lig side may want to tie him to a new deal, the midfielder has been out favour in recent weeks, playing just 38 minutes of his team's last five league games.
Ander Herrera to Valencia
Reports in Spain claim Valencia are hoping to bolster their midfield ranks in the summer with a double signing from Manchester United. The La Liga side are chasing Herrera and Marouane Fellaini, according to El Gol Digital. With Mourinho reportedly keen on reinforcing his options in the middle of the pitch at the end of the season, he may be willing to let the duo depart Old Trafford if he can bring in who he wants.
Iker Casillas to Liverpool
With Roma's Alisson appearing to be Real Madrid's top transfer target for the goalkeeping spot this summer, Jurgen Klopp has turned his attention to Casillas, according to Mi Otra Liga. The 36-year-old is out of favour at Porto, having slipped behind Jose Sa in the pecking order. He has hailed the supporters at Anfield already this season, after he got a good reception when playing there in the Champions League round of 16 tie for the Portuguese side. However, it would be a surprise should he end up at Liverpool, with the Spaniard's best days behind him.
