Transfer fees in football continue to inflate, but the market value of each individual player changes at different rates depending on a variety of factors.

With data sourced from TransferMarkt, these are the 13 players who have seen their market value increase by the most since January 2016.

13. Andrea Belotti – up £21.25m

FC Torino v FC Crotone - Serie A

Change in Value: £4.25m to £25.5m (500%)

Andrea Belotti enjoyed a breakout season in 2016/17, finishing the campaign with 26 goals in Serie A for a Torino side that only placed 9th in the final standings.

The striker has been the subject of transfer speculation this summer, but the club won’t settle for market value and have made it clear they want his €100m (£88m) release clause.

12. Yannick Carraso – up £21.25m

Club Atletico de Madrid v Malaga CF - La Liga

Change in Value: £12.75m to £34m (166.7%)

 

Belgian winger Yannick Carrasco finished the 2015/16 campaign by scoring Atletico Madrid’s goal in the Champions League final and followed that up in 2016/17 with the most prolific season of his career to date – 14 goals in all competitions.

He’s now verging on the elite bracket after a sublime 18 months.

11. Harry Kane – up £21.25m

Hull City v Tottenham Hotspur - Premier League

Change in Value: £21.25m to £42.5m (100%)

A second straight season as the Premier League Golden Boot winner has seen Harry Kane’s market value double from just over £20m over £40m in the last 18 months.

The striker’s real value will come in the future, though, with some research  already valuing the 23-year-old at more than Lionel Messi and Cristiano Ronaldo.

10. Paul Pogba – up £21.25m

Ajax v Manchester United - UEFA Europa League Final

Change in Value: £46.75m to £68m (45.5%)

Although his calculated market value doesn’t yet reach the £89m Manchester United paid for him last summer, Paul Pogba has still seen his worth rise by nearly 50% in 18 months.

That’s certainly a considerable jump when one considers he was pushing £50m anyway.

9. Gonzalo Higuain – up £23.8m

FBL-ITA-SERIEA-JUVENTUS-CROTONE-TROPHY

Change in Value: £39.95m to £63.75m (59.6%)

The latter half of Gonzalo Higuain’s final season at Napoli and his debut campaign at Juventus have coincided with a near 60% on his transfer valuation.

Despite the prolific striker being just six months shy of his 30th birthday, he’s rated at more than £63m.

8. Saul Niguez – up £25.5m

Club Atletico de Madrid v SD Eibar - La Liga

Change in Value: £8.5m to £34m (300%)

The 2015/16 campaign was Saul Niguez’s first as a regular for Atletico Madrid, and after another impressive season in 2016/17, his market value has shot up accordingly.

Increasing by a factor of 300%, 22-year-old Saul is objectively worth four times what he was 18 months ago, a figure that is only likely to increase with time.

7. Antoine Griezmann – up £25.5m

FBL-ESP-LIGA-ESPANYOL-ATLETICO

Change in Value: £42.5m to £68m (60%)

Antoine Griezmann enjoyed a less prolific 2016/17 campaign with Atletico Madrid, but his career has taken a general upward trajectory over the last 18 months and his market value has unsurprisingly shot up by 60% during that time.

He’s agreed a new contract with Atletico which will pay him more money, but rumour has it the same €100m that Manchester United were ready to trigger remains.

6. Pierre-Emerick Aubameyang – up £25.5m

Borussia Dortmund v FC Ingolstadt 04 - Bundesliga

Change in Value: £29.75m to £55.25m (85.7%)

After a season in which he was the Bundesliga’s top scorer with 31 league goals, edging out Robert Lewandowski on the final day, Pierre-Emerick Aubameyang’s market value has virtually doubled since January 2016.

He could well move this summer, although it remains to be seen exactly where.

5. Ousmane Dembele – up £27.84m

FBL-GER-CUP-FRANKFURT-DORTMUND

Change in Value: £210,000 to £28.05m (13,100%)

Now a rumoured target for Barcelona, Ousmane Dembele’s market value stood at just £210,000 when he was still at Rennes in Janaury 2016. Now after a season at Borussia Dortmund’s it has boomed to a shade over £28m.

That’s a ridiculous increase of more than 13,000%.

4. N’Golo Kante – up £28.05m

Chelsea v Sunderland - Premier League

Change in Value: £5.95m to £34m (471.4%)

Back in January 2016, N’Golo Kante was still just a player who had a distant but unlikely hope of helping Leicester win an unprecedented Premier League title. Now, 18 months later, he’s a player that has two in his collection after doing more or less the same for Chelsea.

Kante appears to be one of the few top players whose objective market value actually mirrors their transfer fee – Chelsea paid £2m less than what he is currently worth.

3. Kylian Mbappe – up £29.71m

FBL-FRA-LIGUE1-MONACO-TOULOUSE

Change in Value: £40,000 to £29.75m (69,900%)

Kylian Mbappe had only just turned 17 years of age in January 2016 and was at that point still yet to score his first senior goal for Monaco. He wasn’t even on a professional contract at  the time and so his market value was just £40,000.

That has all changed in 18 months, though, with a near 70,000% increase.

2. Dele Alli – up £29.75m

FBL-ENG-PR-TOTTENHAM-ARSENAL

Change in Value: £4.25m to £34m (700%)

For the second season in a row, Tottenham starlet Dele Alli struck double figures in front of goal in 2016/17. But more than just reaching that milestone again, the youngster more than doubled his tally from 10 in 2015/16 to 22.

The sky appears to be the limit for Alli, who has already been linked with Real Madrid.

1. Paulo Dybala – up £31.54m

Bologna FC v Juventus FC - Serie A

Change in Value: £23.8m to £55.25m (132.1%)

No player in world football has seen their value increase more in terms of monetary amount over the last 18 months than Juventus forward Paulo Dybala.

The Argentine international established himself as a world class player as Juve won a domestic double in 2016/17 and reached the Champions League final.
