Florentin has officially joined the MLS champions this week after there was much speculation that Romelu Lukaku's brother Jordan was signing for Newcastle United during the transfer window.
While there is a long history of brothers representing the Reds, such as Brian and Jimmy Greenhoff and Gary and Phil Neville, we are focusing on current members of the first-team squad and their sporty siblings.
PAUL, FLORENTIN AND MATHIAS POGBA
Our World Cup-winning midfielder has two brothers in the professional game. Florentin played against Paul in the Europa League ties with Saint-Etienne in 2017. The powerful 28-year-old joined Elche on trial last month after previously being with Genclerbirligi in Turkey, but has ended up moving Stateside.
