Not because it helped secure Arsenal's second trophy in two seasons while Liverpool continue to sit empty handed (although that may have played a part too).
No, Carragher humorously took to Twitter in response to Walcott's goal with regards to Liverpool's chances of signing the speedy 26-year-old.
Indeed, Liverpool winger Raheem Sterling wants to leave the club this summer and Walcott is yet to agree a new deal with Arsenal. A swap deal could make sense for some, then, but not anymore, according to the Reds icon. He tweeted:
That's the swap deal with Sterling out of the window!— Jamie Carragher (@Carra23) May 30, 2015
And, in all seriousness, Carragher may have a point - even if he's only joking.
Any doubts Arsene Wenger had about Walcott's ability to lead the line for Arsenal may have been allayed after his hat-trick against West Brom and the FA Cup final performance against Aston Villa that followed.
It is simply a case of keeping the 26-year-old fit all season, something that has proven mightily difficult in recent years - the same problem Liverpool currently have with Daniel Sturridge.
