Arsenal fans found an old tweet posted by one Nottingham Forest star after his side lost to Manchester City.
Forest began the day one point above the relegation zone, having found wins hard to come by in recent weeks.
But they were unlucky not to come away with something in their eventual 2-0 defeat to City, with Chris Wood miscueing an effort from 12 yards that would have drawn them level.
Wood was clearly devastated with the miss - but it was a rare blip in what has otherwise been an excellent campaign for the striker thus far.

The New Zealand international has been a key player for Nuno Espirito Santo's side this season, netting 12 goals in 28 league appearances. Should Forest stay up, a fair amount of the credit will have to go to him.
But the clash against City was an emotionally-charged one for Arsenal fans, who were hopefully of a positive result for the hosts at the City Ground to aid their own Premier League title fight.
The Gunners are now one point clear of City following their 3-2 win over Tottenham earlier in the day, but Pep Guardiola's side have a game in hand on their title rivals.
Last year, meanwhile, Wood came off the bench to rescue a point for Forest against City in February - a result that dropped City behind Arsenal in the Premier League title race before they ultimately went on to win it.

But that appears to be a case of short memories for some Arsenal fans, who took to Wood's Twitter account following his miss in the game - and found an old tweet about Manchester City.
The tweet is timestamped at shortly before 10pm on April 30, 2012 - around the time that the full-time whistle blew to signal City's 1-0 win over Manchester United in the Premier League.
Wood was on loan at Championship side Bristol City that season, but as their campaign had finished two days earlier (and they finished 20th), Arsenal fans associated it with being about Manchester City - although it should be noted that he hasn't actually tweeted about the club for 10 years since then.

Speaking about Wood's miss on Sky Sports, former Nottingham Forest defender Michael Dawson said: "There's plenty of positives they can take from this.
"They had great opportunities, and I'm sure Chris Wood, who has been in a great vein of form, will have a sleepless night tonight."
