It's good to see camaraderie running high amongst players at club level, even when they're not together on international duty.
And this weekend saw Liverpool defender Ragnar Klavan show that the team spirit at Anfield is high even when their key players are scattered across the globe for a week.
While key forward Roberto Firmino has been doing the business on the pitch, he has been the subject of some minor ridicule for his outlandish personal style.
And nothing is more open for criticism than a person's hair...apparently. This season has seen the Brazilian sporting a trendy top knot, which is clearly giving his teammates a source of great amusement.
Klavan joined Liverpool over the summer from German outfit Augsberg, and despite being one of the new boys he clearly feels no problems with giving one of his more established teammates a bit of the old banter.
While away with Estonia this week, Klavan donned a hat that reminded him of the Reds forward and paid a little tribute to him by recreating the now infamous top knot.
"Greetings to @roberto_firmino from cold Estonia, tried your hairstyle today in the training, looks great now only things missing are the mad skills," the 31-year-old said.
Klavan is in Talin for a difficult fixture against a strong Belgium side on Sunday, and though Estonia have the potential to be a banana skin, they are already six points off the pace behind Roberto Martinez's men.
However, over in South America, Roberto Firmino already seems to be close enough to booking a place at the 2018 World Cup.
The Selecao were already top of their group and thanks to a 2-0 win over Argentina over the weekend.
Firmino came on from the bench to feature as a second half substitute, but watched on as his club mate Philippe Coutinho scored a wonder goal to help shock their rivals.
However, it could be a case of no rest for the wicked as Firmino is expected to be involved again on Wednesday this week as Brazil take on Peru.
