The transfer window for Europe's biggest clubs is open again. Transfer Talk has been scouring the world's media and setting our correspondents loose to see who could be heading to/out of your club this month.
Chelsea inquire about Barcelona flop Coutinho
He's been at Barcelona for only a little over a year, but already things have turned sour for Philippe Coutinho. The 26-year-old has not been able to force his way into Ernesto Valverde's side on a regular basis, starting just 10 La Liga fixtures this term.
Speculatively linked with Manchester United last week, the former Liverpool attacker could still be offered a Premier League lifeline, with a report from the Daily Express claiming Chelsea have asked after his availability.
The Londoners have been quoted a reported £100 million for Coutinho, who cost the Catalans £142m when he joined a year ago.
Real Madrid's Silva service
If one man has benefitted from Kevin De Bruyne's injury woes at Manchester City this season, it's Portuguese schemer Bernardo Silva. The 24-year-old had to be patient after joining from Monaco in the summer of 2017 but has come into his own this term with the Belgian seeing limited action.
Real Madrid have taken note of Silva's fine form for Pep Guardiola's side and, according to the Daily Mirror, will make a move this summer.
The report in Sunday's edition goes on to claim the Spanish giants' interest could force the Premier League champions to open talks over a new deal. Silva is contracted until the summer of 2022.
Dortmund intent on keeping Sancho
Jadon Sancho has been one of the breakout stars of the season and a key player in Borussia Dortmund's remarkable title bid.
Naturally, talk of a big-money move has started to emerge. But BVB are adamant they will hold onto the teenage forward beyond the summer. Among those linked already are Manchester City -- the side he left to join Dortmund for just £7m just two summers ago.
"Jadon Sancho will stay with us in the next season," sporting director Michael Zorc told SportBild. "He has great quality and is a bet for the future, he will remain in Dortmund."
Emery drops hint over Suarez reunion
Arsenal boss Unai Emery has already admitted Arsenal can afford only to make loan signings this month, limiting their capabilities in the market.
However, the Star says one target who is available on loan is Barcelona midfielder Denis Suarez. The 25-year-old is known to Emery, having played under him at Sevilla and, handily, is well down the pecking order at the Camp Nou, meaning he would be allowed to leave this month.
Asked about the possibility of signing the Spanish midfielder following his side's 2-0 victory over Chelsea on Saturday, Emery said: "I know the club is working with different possibilities if [it] can help us for these four months for our competition."
Asked whether Suarez might be signed in time for his side's FA Cup fourth-round tie against Manchester United on Jan. 25, Emery replied: "I know it's a difficult window for the transfer market, and if a player is coming to help us I am happy. But the club is doing that and I am going to wait."
Football Whispers' transfer algorithm gives the likelihood of rumours happening a score out of 5.
Weston McKennie to Liverpool: 2.8
Jurgen Klopp knows the Bundesliga better than most and could be about to return to his homeland to sign United States and Schalke powerhouse Weston McKennie, according to the Sun. The 20-year-old midfielder, who can also play at centre-back, could be available for around £20m.
Christian Eriksen to Chelsea: 1.5
While Harry Kane continues to dominate the headlines, the Danish playmaker struggles to get the credit he deserves for his quietly brilliant performances behind the England captain. But his quality has not gone unnoticed, with Chelsea joining Real Madrid in expressing an interest, according to the Daily Mirror.
Aaron Wan-Bissaka to Manchester City: 1.4
It's been a while since Wilfried Zaha and Nathaniel Clyne came through Crystal Palace's much-vaunted academy. Now the South Londoners have another talent on their hands in Wan-Bissaka. The 21-year-old has made the right-back spot his this season and, according to the Times, Manchester City are keen to swoop.
Carlos Vela to Barcelona: 1.2
The Mexico international was never a regular for Arsenal and finally left for Real Sociedad in 2012 after five loan spells away from the Emirates. Now 29, he spent last season in Major League Soccer with LAFC, bagging 14 goals and supplying 11 assists. According to ESPN Deportes, Vela is now a surprise loan target for Barcelona.
Hirving Lozano to Arsenal: 1.2
One of the stars of the World Cup as Mexico reached the round of 16 before crashing out -- as usual -- the PSV Eindhoven forward has carried his form into this season, scoring 11 goals in just 17 Eredivisie starts. That form, according to Tuttomercato, has prompted interest from Arsenal. The North Londoners face competition from Napoli, Chelsea and Real Madrid.
