The trouble was, on this occasion, I was also providing updates on the match for United’s official Twitter account and had forgotten to log out and switch profiles on the day afterwards, when following Guruzeta as planned.
The realisation that I had added a rival player to the Reds’ list of pretty exclusive names the club were following caused the colour to drain from my face and a shiver to run down my spine. Even though it had only been a matter of about half an hour or so, I am fully aware of the fuss a simple error of judgement like this can cause. I quickly dreaded speculative transfer stories claiming United were now chasing the signature of the Basque youngster popping up all over the web.
A panicked call to the communications department to own up to the mistake was followed by a nervous wait to see if this could have been yet another excuse to add to the never-ending rumour mill concerning the Reds and potential new signings.
Thankfully, I got away with it. The centre-forward, who had played with levels of aggression and commitment that really impressed, would only be followed on my personal account, going forward.
