Ajax’s record signing Sebastien Haller was mistakenly left off their Europa League list, the club have confirmed.
Clubs competing in the Europa League round of 32 submitted their final squads, which consists of up to 25 players, on Wednesday, but Haller was not included in Ajax’s list.
“It is indeed true that Haller is not on our Europa League list of players,” an Ajax spokesperson told ESPN NL. “We are working with the KNVB and UEFA to find out where things went wrong.”
It is not clear whether the error was caused by Ajax, the Dutch FA or UEFA but if the club are at fault, they will not be able to amend the situation.
There were other discrepancies with the submitted lists as Siebe Schrijvers’ name appeared twice in the section of players excluded from Belgian side Club Brugge on UEFA’s website. He left to join Waasland-Beveren on loan in January.
Ajax were drawn against Lille in the Europa League round of 32 and will play for the first leg in France on Feb. 18.
Haller joined Ajax from West Ham United in January in a club-record £20.5 million deal and made his debut against PSV Eindhoven, where his introduction at half-time helped turn a 2-0 deficit into a 2-2 draw.
The 26-year-old has scored two goals in six games for his new club and would have been a certainty to make the list.
