Friday night was a good night for one ex-Arsenal star as he notched an international hat-trick on debut.
Serge Gnabry, who left the Emirates for Werder Bremen over the summer, was on the scoresheet three times as Germany thumped minnows San Marino 8-0 in World Cup qualifying.
And the Bundesliga side couldn't help but aim a thinly-veiled dig at the winger's former employers.
Their tweet pointed out that Gnabry had made his international bow, scored a hat-trick and featured in an 8-0 win, before tagging the Gunners in the tweet with a winking emoji.

But it was Arsenal who had the last laugh, retorting: "On the subject of hat-tricks, remember this?"
The tweet was accompanied by a picture of Ray Parlour celebrating his treble in a UEFA Cup tie against Bremen in 2000.
Gnabry has starred in the Bundesliga since his £5million switch, scoring four times and laying on another in nine matches so far, although Bremen are currently languishing in 16th.

Parlour's hat-trick at the start of the century featured a superb strike with the outside of his boot, another which saw him beat three defenders before a simple one-on-one completed his treble.
They win helped Arsenal to the semi-finals of the competition after they had won the first leg 2-0 at Highbury.
