Two African players from Viborg FF will not be able to travel for their Europa Conference League play-off against West Ham United due to English entry rules for non-EU citizens after Brexit, the Danish club says.

Nigerian winger Ibrahim Said and Gambian forward Alassana Jatta will have to stay behind as the club could not secure visas for the two players ahead of Thursday's first leg at London Stadium.

"We have tried everything, and have been in close contact with DBU (Danish football association), UEFA, the two embassies and another foreign club which has been in a similar situation," Viborg said in a statement.

"But unfortunately it has proved to be impossible, as there is a processing time of several weeks and the match was only finally scheduled a week ago."

Viborg qualified for the play-off round after coming through the qualifying rounds in July and August.

"It's a shame from a sporting point of view as both players would have had a role in the match," said Jesper Fredberg, the club's sporting director.

"But it's even more of a shame from a human point of view that these two are missing out on this great experience."

Ahead of the first leg, West Ham announced the signing of defender Thilo Kehrer from Paris Saint-Germain with the Germany international signing a four-year contract.

The 25-year-old made 34 appearances for PSG in all competitions last season.

Kehrer is capable of playing either as a centre back or as a full back while he has also been deployed as a defensive midfielder.

"He's a talented player, who can play in a number of defensive positions, adding strength and depth to our current options," West Ham boss David Moyes said in a statement.

Kehrer has also been a regular starter for Germany ever since Hansi Flick took over the national team last year.

He is West Ham's sixth signing since the close season after defender Nayef Aguerd, goalkeeper Alphonse Areola, centre forward Gianluca Scamacca, winger Maxwel Cornet and midfielder Flynn Downes.
