Victor Moses may be thriving at right wing-back, but having never played there before this season, it’s understandable that Antonio Conte may be looking at other players for that position.
But what would the 22-year-old bring to Chelsea? We've taken a look.
Who is João Cancelo?
The right-back was born in Portugal in 1994 and joined Benfica’s youth team aged 14 in 2007.
He progressed through the ranks before making his debut in January 2014, coming on as a late substitute in the Portuguese League Cup, before making his league debut against Porto in May of that year.
That turned out to be his only league appearance for the Lisbon club, as in August 2014 he joined Valencia on a one-year loan deal, making 13 appearances in all competitions.
He did enough to convince Los Che to part with €15million to bring him in permanently the following summer.
Since then, he’s become a regular at the Mestalla and has even started to be used further up the pitch as a right winger.
Cancelo has made 81 appearances for Valencia, scoring three times and getting seven assists.
He has also been sent off three times since moving to Spain, but has never received a straight red card.
The Portuguese, who made his international debut in August, is known for his tremendous energy – something Antonio Conte would love – and he is a dangerous threat for opponents.
His crossing is decent and he has been known to take Valencia’s corners.
Defensively, he is also improving, and Conte would like his flexibility – as well as playing further forward, he can play at left-back.
How much would it cost Chelsea to buy him?
Valencia are a club that seems to be constantly in financial turmoil.
Their Nou Mestalla stadium, which should have opened in time for the 2009-10 season, is still sitting partially completed due to financial problems.
This has meant throughout the years, they have always been a selling club – they have never been afraid to sell their best players if the price is right, just look at David Villa, Juan Mata, Jordi Alba, Roberto Soldado and David Silva.
And Deporte Valenciano suggests they may consider selling Cancelo for €30million (£26million) in the summer in order to rebuild their squad after what’s been a pretty disastrous season, with Los Che sitting 13th in La Liga.
That €30million price tag definitely won’t scare off Chelsea, especially with their new deal with Nike and the money they have yet to spend from selling Óscar to China.
But they will more than likely have to compete with Barcelona, who will be looking for a new right-back with Sergi Roberto failing to impress and doubts over Aleix Vidal despite his impressive form before dislocating his ankle.
Is there space for Cancelo at Chelsea?
The right wing-back spot is probably an area of weakness in terms of strength in depth for Chelsea.
Moses has been brilliant, but beyond that, there is no-one proven in the squad who has played there before.
César Azpilicueta has been shifted there when Kurt Zouma comes on as a substitute for Moses late on in matches, but do you really want to take the Spaniard out of the role in the back three where he has been thriving so much?

The only other player in the Blues’ squad who could play there would be Ola Aina.
At 20, he is only two years younger than Cancelo, is inexperienced, and is yet to start a league game – it would be no surprise to see him follow the likes of Izzy Brown, Tammy Abraham and Kasey Palmer in going out on loan and getting first-team experience in the Championship.
Cancelo’s qualities as an attacking right-back would make him perfect for a right wing-back role.
How does João Cancelo compare to Victor Moses?
Both Cancelo and Moses have had a similar amount of game time this year.
They have both played 26 league matches, while Cancelo has been involved in 1864 minutes, Moses has featured in 1842.

Dribbling is a key element for a wing-back, and Cancelo makes a much larger number of dribbles per 90 minutes – 4.7 compared to 3.2.
But it is the Nigerian who is much more successful with his dribbles.
Moses has one unsuccessful and 2.2 successful dribbles per 90, whereas Cancelo’s stats work out 2.3 unsuccessful and 2.4 successful dribbles.
They make a similar number of passes per game – the Valencia man has made an average of 37.6 in the league this season, while Moses has made 37.3.
But the Chelsea man comes out on top in terms of pass accuracy – 78 per cent compared to 72 per cent.
However, probably unsurprisingly given him having a more defensive background, Cancelo makes more successful tackles per 90 minutes – 2.41 compared to 1.42.
Moses does make more clearances per 90 minutes though – averaging 2.9 so far in the league compared to the 1.7 averaged by the Portuguese.
Cancelo is yet to score in the league so far this season – Moses has three.
That’s not a surprise given Cancelo plays slightly further back than Moses, and has taken 0.6 shots per 90 minutes, compared to the Nigerian’s 1.5.
They both have two assists under their belt.
A good signing?
Cancelo is still 22 and has a lot of learning still to do.
Indeed, he isn't the most popular of Valencia players among the fans – with many seeing him as a symbol of Jorge Mendes' influence at the club.

But Conte has shown himself capable of taking players to the next level – just look at how Moses and Pedro have improved this season.
You would doubt whether he would want to forgo a first-team place after being a regular at Valencia, but the lure of Chelsea could prove too much, especially when you consider Los Che won’t be anywhere near European football next season.
If Moses drops off in form, with Cancelo, the Blues would have a ready-made replacement, and if signing another option for right wing-back takes the Nigerian to the next level, it would only benefit Chelsea.
