Leeds United manager Marcelo Bielsa has refused to rule out spying on opponent's training sessions in the future after admitting to sending a member of staff to watch Derby County ahead of last night's 2-0 victory at Elland Road, report the Yorkshire Evening Post. 

The man was spotted at the Rams' training complex on Thursday morning and was subsequently removed by police, with Bielsa admitting before the match that he was responsible for the move.

However, having apologised to Frank Lampard, Bielsa refused to rule out using the tactic in the future:

"If I said that [would not use spies in the future], I would lose credibility,” he said.

“I won’t say that I won’t do it again. It’s a childish position to answer like that.”

The FA are continuing to investigate the incident.

On the pitch, the home side could have had a penalty just seconds into the game when Ezgjan Alioski was bundled over by Andre Wisdom in the Derby area but the linesman had, incorrectly, judged the Leeds left-back to be offside.

Kemar Roofe gave Leeds the lead in the 20th minute, however, tapping home after some brilliant work from winger Jack Clarke following a poor Scott Carson punch.

It was 2-0 just two minutes into the second half has Carson once again could only claw Clarke's cross straight to the feet of Alioski who squared for Jack Harrison to tap home to secure all three points.

The verdict 

I must admit I find the whole 'spygate' controversy utterly brilliant. I love it.

Aside from trespassing, which is obviously bad, I do not think Leeds have done anything wrong. They wanted to gain an advantage and did what they could to do so.

I think it has been hijacked by people who simply love to get absolutely livid about anything they can when in reality it does not matter that much.
