Romelu Lukaku’s transfer value has increased the most since July 2017, according to figures from the CIES Football Observatory.
The website values players based on “inflation, expensive transfers to other teams, contract extensions and top level performances”, among other things. It is therefore no surprise to see Lukaku’s value increase so dramatically, from £91m to £140m, as he made an expensive summer transfer, received a new extended contract and started the new season well.
Two of those three things are also true for Alex Oxlade-Chamberlain, and he therefore also saw a big jump in value, from £24m to £52m. This put him fifth on their list of the top increases.
Down at 34th is the highest Arsenal player in their top 100, with Alexandre Lacazette’s value moving from £57m to £71m. In fact, Lacazette is the only Arsenal player who makes the list at all, after his club record move to the Gunners earlier in the summer, and his four league goals so far.
Players like Alexis Sanchez and Mesut Özil will have benefited from inflation, but the lack of an expensive transfer and their contracts running down explain their lack of inclusion.
Meanwhile, Arsenal’s only other summer signing, Sead Kolašinac, was brought in on a free, so again there’s no surprise that he didn’t make it in.
