Derby County are involved in a huge match on Friday evening.
The Rams will travel to Elland Road to take on Championship leaders Leeds United.
Currently sixth in the table, Derby will be looking to make it four defeats in a row for Marcelo Bielsa’s side.
As such, Frank Lampard would’ve hoped his preparations for the match went smoothly.
Sadly for him, that’s not been the case.
The Derby boss was forced to stop a training session on Thursday amid concerns a spy was at the club’s headquarters.
Indeed, police were called after reports that a man was acting suspiciously at the training base.
Police called to the scene
According to the Daily Mail, the male was in possession of a pair of binoculars, pliers and a change of clothes.
Police brought an end to the training session as they carried out checks upon their arrival.
Derbyshire Constabulary wrote on Twitter: “Officers have just attended the Training Ground for @dcfcofficial After a suspicious male was seen at the perimeter fence.
“Excellent searching conducted & male was located. All checks above board!”
“Keeping the team safe to bring home a win against #LUFC on 11th! #SpyingIsCheating”.
The man was later released after being questioned.
Hardly ideal preparation for Lampard ahead of such a big game.
Leeds beat Derby 4-1 at Pride Park in August but the former Chelsea boss believes his squad is stronger now.
“I do think we have come on, and we have worked hard to do that," Lampard told the club's website.
"We have changed a bit; our style of play, slightly, and our personnel, definitely, so let’s try and show that we are a different team to the one that lost 4-1 in the second game of the season.”
Bielsa’s Leeds are looking for their first win in four matches.
Defeats in the league against Hull and Nottingham Forest were followed up a 2-1 loss to Queens Park Rangers in the FA Cup third round.
