Freddie Ljungberg takes his Arsenal side to West Ham United on Monday as his two former Premier League clubs clash.
Yes, because while Ljungberg is an Arsenal legend, they're not the only English side he turned out for.
Even if only West Ham fans remember it.
The Swede moved there after nine years at Arsenal, primarily, it seems, because he saw the rest of the 'Invincibles' leaving the club.
"I felt like all the unbeaten players had left," he said after joining the Hammers. "I wanted to be loyal but I felt like it was the right time."

And so the two-time Premier League winner moved across London to join the project at West Ham on a four-year contract.
He would not see out that contract - not even close.
Ljungberg played 26 games in what proved to be his first and only season at West Ham, starting 22 times.
He only scored twice - although, they probably should have seen that coming as he only scored twice in each of his last two years at Arsenal.
Unfortunately, the limited appearances and goals can be put down to injuries.
Ljungberg suffered every injury over the sun - from muscles injuries to migraines - and eventually saw his season end from broken ribs.
To sum up then, things didn't go well and it was announced at the end of the season that Ljungberg would be leaving with three years left to run on his contract.
It cost West Ham £6m in severance pay to end the deal prematurely but the feeling was it suited everyone.
"I gave my all at West Ham and enjoyed my time there but the decision is the best for the both of us," Ljungberg said afterwards. "Now, I will take my time to consider my football future."
And with that, the Swede was gone from the Premier League.News Now - Sport News
