Arsenal transfer target Shkodran Mustafi was told that he would have to sign for the Gunners if he wanted to enter the UK.

As defender arrived at Gatwick airport with his club Valencia ahead of their two-game tour of the country, one staff member took the opportunity to use his position to benefit his beloved football club and jokingly threatened the German defender with rejection.

Spanish publication Marca quoted the unnamed Gatwick Airport official. He said: “Sign for Arsenal or else you aren’t coming through.”

Mustafi was allowed into the country and reportedly took the joke well after being strongly linked with a move to Arsenal.

The north London outfit have been looking to bolster their defensive ranks after a spate of pre-season injuries have left them short at the back, with Per Mertesacker ruled out for up to five months.

Arsene Wenger has admitted that he is in the market for a new centre-back and The Sun have reported that the Gunners have already made a £15million bid for Mustafi.

The 24-year-old has won 12 caps for his country after establishing himself as a regular for his La Liga side since his transfer from Sampdoria in 2014.

The former Everton academy graduate featured for the World Cup winners at Euro 2016 and scored in the opening match against Ukraine, which his team won 2-0.

Mustafi has three years left on his current deal in Germany but could be tempted by a move to the Premier League.
