First and foremost, it set United on their way to a 12th home-league win of the season, whereby they extended their lead at the top of the league table to 12 points following Manchester City's defeat to Southampton on Saturday.
Secondly, and on a personal level for Giggs, it meant that he kept up his excellent record of having scored in every single Premier League-era season, 21 in total to date.
The Welshman, now aged 39, had scored in both the League and FA Cups this season, but was without a domestic league strike after more than a dozen appearances. But against Everton—the seventh time he has scored against them—he made sure that his record is at least that little bit longer. Consider this tweet from Opta Sports:
21 - Giggs has now scored in each of the 21 PL seasons, it is his 7th goal v Everton in the PL (he's only scored more v Spurs-10). Eternal.— OptaJoe (@OptaJoe) February 10, 2013
Having started his United career in the pre-Premier League era, Giggs has now in fact scored top-flight league goals in England for 23 successive seasons.
It will be the three points for his team, though, which are rather more important at this point. City's defeat to Southampton almost surely ends their lingering title challenge, which they will give up having won their first Premiership trophy last season.
Only a massive drop in form could see United throw away their mammoth lead with 12 games to go, and it looks as though Giggs will be on his way to winning his 13th Premier League title with Manchester United come May.
