PIERRE-EMERICK AUBAMEYANG
Incredibly quick and utterly unstoppable in the Bundesliga, Aubameyang might be Manchester United's ideal acquisition, apart from the "galacticos" they waste their time chasing.
The 26-year-old Gabon striker has scored 27 goals in 26 games for Borussia Dortmund this season. The difference with United, who have only scored 10 times in their last 14 matches, is stark.
ALEX TEIXEIRA
The top scorer in the Ukrainian league, Texeira has 22 goals in 15 games. They are figures a low-scoring Chelsea team can only envy.
The Brazilian may cost around £30 million (S$62 million) and Paris Saint-Germain and Juventus are also reportedly keen on the Shakhtar Donetsk forward, so his arrival would be a coup for Guus Hiddink.
NEVEN SUBOTIC
A stalwart of Juergen Klopp's Mainz and Borussia Dortmund teams, Subotic was a logical target for Liverpool even before Martin Skrtel suffered a hamstring injury.
The reality is that Liverpool ought to have signed a right-sided centre-back earlier - last summer at the latest - and securing the Bosnian international should be Klopp's top priority.
EDINSON CAVANI
It is rare for players of Cavani's calibre to move in January, but he has been upstaged by Zlatan Ibrahimovic and Angel di Maria at Paris Saint- Germain and the club may be tempted to cash in before his value drops.
Arsenal have been linked but may object to a mooted fee of £47 million and high wages. Man United, with a desperate need for a centre- forward, are likelier to pay the price.
GRZEGORZ KRYCHOWIAK
Even the ever-stubborn Arsene Wenger, who dislikes being told to spend, admitted Arsenal needed a defensive midfielder when Francis Coquelin was injured. He has since moved to sign Basel's Egyptian Mohamed Elneny.
But Sevilla's Poland international Krychowiak, who has attracted his attention before, would give them a higher-class alternative. A Europa League winner, the 25-year-old is both physically imposing and an accomplished passer.
JACKSON MARTINEZ
The Colombian's agent said that Chelsea are interested in his client, possibly in a swop deal that would see Diego Costa return to Atletico Madrid.
While Martinez has struggled for Atletico and Chelsea like his team-mate Antoine Griezmann, they need a powerful, quick striker and the 29-year-old, who scored 92 goals in three years at Porto, fits the description.
FELIPE ANDERSON
Louis van Gaal keeps lamenting about a lack of pace on the flanks for United and, besides speed, Anderson offers dribbling ability and the possibility of at least 10 goals a season.
The 22-year-old Brazilian could earn Lazio around £33 million, but money is no problem for United, who need more creativity.
JUAN ITURBE
A talent whose potential is not being exploited, Argentinian winger Iturbe cost Roma €25 million (S$38 million) last year. He has started three Serie A games this season, however, and has English admirers.
Bournemouth have been linked with him but Watford, who have greater experience of recruiting from Italy, would be a better fit. Their prolific strikers Troy Deeney and Odion Ighalo might appreciate Iturbe's service.
RUBEN NEVES
The youngest-ever captain in the Champions League, Porto's 18-year-old holding midfielder shows precocious maturity and an assurance in possession.
There are suggestions Liverpool are interested, but given Cesc Fabregas' decline this season, Chelsea may want to pair him with Nemanja Matic. He would be a better option than John Obi Mikel.
STEVE MANDANDA
Marseille lost several of their star players to Premier League predators last summer. Another could depart. Mandanda has been linked with Aston Villa, which is something of a poisoned chalice.
But, while Liverpool are strangely keen to give Simon Mignolet a new contract, his frailties, especially against set-pieces, are increasingly apparent. France international goalkeeper Mandanda could give Juergen Klopp more solidity.
