Security is being stepped up at Premiership football grounds in the wake of the London terror attacks ahead of the new season, the BBC has learned.
Premiership clubs have long been concerned they may be targeted
All 20 Premiership clubs are taking extra measures, such as searching all bags brought into stadia on match days.
This is expected to lead to delays at the turnstiles, so fans are being urged to avoid bringing bags or to allow extra time to get into the ground.
Some clubs are running staff training courses and boosting CCTV surveillance.
Security was tight for the traditional curtain-raiser to the football season, the Charity Shield match between Chelsea and Arsenal last weekend.
Police did not receive intelligence warning of a terrorist threat, but wanted to reassure fans of the two London clubs for the game at Cardiff's Millennium Stadium.
And in April last year, security was tightened at Old Trafford when Manchester United played Charlton, following media claims the match was to be the target of a terrorist attack.
A number of clubs attended a summit last July, to discuss planning for a chemical, biological or nuclear attack.
