When a football great like Steven Gerrard retires, it's customary for ex-teammates and fellow professionals to pay tribute on social media.
That was once again the case on Thursday afternoon, with the likes of Xabi Alonso, Luis Suarez and Jamie Carragher congratulating the former Liverpool captain.
Even Iker Casillas and Kaka, who have both played against Gerrard at some point in their careers, wished the 36-year-old well on Twitter.
Attached to a picture of himself and Gerrard holding the 2005 Champions League ball, Kaka wrote: "We were rivals and we lived unforgettable finals. Steven Gerrard congratulations on your incredible career."
Wayne Rooney has now become the latest to pay homage to Gerrard, who he played with and against for the England national team and Manchester United respectively.
The 31-year-old isn't renowned for being good with words but, credit where it's due, he absolutely nailed his tribute (see below).
He wrote: "One of the best I've played with. One of the best I've played against. One of the best there has ever been. Enjoy your retirement mate."
A lovely message, I think you'll agree, but that didn't stop Rooney from being unnecessarily abused on Twitter by United fans.
While some urged the captain to delete his tweet, others suggested it wouldn't be long before he retires and that it should be him hanging up his boots, not Gerrard.
One user had the perfect response to those ridiculing Rooney.
Well said. Rooney hailed Gerrard as one of the best he's played with but, in 2015, he named the Liverpool legend as the best England player he's ever played alongside.
"I'd have to say Stevie [was the best]," he said, per Squawka. "For me, he's an incredible player; an incredible leader.
"He helped me a lot during my early days with England."
Knowing United fans, they're probably still angry at Rooney for not naming Paul Scholes as his best ever England teammate.
