ANDREA BELOTTI (TORINO)
Real Madrid's Spanish striker Alvaro Morata remains top of Manchester United's most-wanted list but the club have also been keeping an eye on this young Italian.
Strong and relentless, Belotti has scored 40 goals in 73 appearances since joining Torino two years ago and AC Milan have already seen one bid turned down for the 23-year-old striker.
Torino are holding out for as much money as possible.
DOUGLAS COSTA (BAYERN MUNICH)
The Brazilian winger fell out of favour in his second season at Bayern and has also clashed with the club's new board during negotiations for a fresh contract.
But there is no doubting the 26-year-old's talent and Juventus are poised to take advantage of Costa's situation by taking him to Turin.
VIRGIL VAN DIJK (SOUTHAMPTON)
The centre-back remains in demand despite Liverpool ending their interest in him after Southampton reported them to the Premier League for an alleged illegal approach this month.
Chelsea and Manchester City continue to monitor the 25-year-old Netherlands international, who has been outstanding since his move from Celtic two years ago, but the asking price of £60 million (S$105.9 million) may be a stumbling block.
PIERRE-EMERICK AUBAMEYANG (BORUSSIA DORTMUND)
The speedy forward, who has scored 113 goals in his four seasons with the German side, would make a fine addition for any team in Europe.
The 28-year-old has been heavily linked with both Man United and Man City, and he would be an obvious replacement for Diego Costa at Chelsea. But those close to the Gabon international have said his dream is to play for Barcelona or Real Madrid.
NELSON SEMEDO (BENFICA)
The Portuguese champions could do with hanging on to Semedo after selling Victor Lindelof to Man United and hope that an exorbitant asking price will deter clubs.
However, Barcelona need a new right-back. They have been chasing Arsenal's Hector Bellerin, but Semedo also features on their list.
The 23-year-old is already a Portugal international and has been linked with United, who could pounce if Barcelona fail to make their move.
MARCO VERRATTI (PSG)
Barcelona's desire to sign the Italian is easy to understand. Verratti might not score many goals or win many awards, but he is a midfielder with a deep understanding of football, a player who can control games with his technique, anticipation and passing.
It is clear to see how the 24-year-old would fit in at Barcelona, who believe that he can be the long-term replacement for Xavi Hernandez.
