They may be heroes with rival London clubs, but the mutual respect between Diego Costa and Thierry Henry goes beyond club boundaries.
Chelsea striker Costa met former Arsenal forward Henry on Thursday, and the Brazilian seemed delighted to have met one of the Premier League's deadliest marksmen.
He shared a selfie of the pair of them on Instagram, with the caption: 'Great afternoon today being interviewed by the amazing star Thierry Henry'.
While it was Henry doing the interviewing, Costa may well have wanted to ask a few questions of the Frenchman about finishing as he struggles to break an uncharacteristic goal drought.
