Romelu Lukaku is now worth a remarkable 54 percent more than he was when he joined Manchester United in July.

The Belgian striker has made a fantastic start to life at Old Trafford, with seven goals in his first seven Premier League games for the Red Devils. Even so, the jump in his transfer value is remarkable.

According to a study from the CIES Football Observatory, Lukaku's market price has gone from €102.7million on 1 July - a few days before he completed his move to United - to €158.5million on 1 October.

Swiss football research group CIES specialise in the scientific estimation of player's transfer value and their latest release comes after a record breaking summer of transfer action across Europe.

Interestingly, Lukaku's massive jump means that, according to CIES, he is now worth more than Kylian Mbappe.

Mbappe is technically on loan at PSG this season, but the French giants have already agreed a £166million fee with Monaco ahead of a move next summer.

However, the CIES figures have Mbappe's current value at €145.8million. That means, despite Lukaku 'only' costing £75million a few months ago, his outstanding form has already seen him go past the French wonderkid in the transfer value rankings.

Another note of interest is Alex Oxlade-Chamberlain's transfer value - which has more than doubled over the past three months.

The England midfielder joined Liverpool from Arsenal at the end of the summer transfer window in a £35million move and is yet to start a match for the Reds in which they have won.

CIES had the former Arsenal man valued at €27million on July 1, but have now re-assessed that to €58.7million, despite a rough start to life at Anfield.

Paulo Dybala (€47m) and Ousmane Dembele (€45m) are the other big risers.

Mohammed Salah, Kevin de Bruyne and Marcus Rashford also make the top ten.
