Premier League leaders Liverpool could make some extra money added to the already humongous payout that they received in return for letting Philippe Coutinho move to FC Barcelona in January.
Coutinho's deal with Barcelona included performance related bonuses amounting to an additional £36m that Liverpool will earn if things go per plan.
The Reds have already triggered two of such bonuses in the deal amounting to as much as £8.8m. However, there are still £27.2m up for grabs and the Anfield-based club wants three things to happen if they are to earn this amount.
The first variable clause that was included in Coutinho's deal to Barcelona included the number of appearances. Mirror report that Barcelona agreed to pay Liverpool £17.6m once Coutinho completes a total of 100 appearances for the Catalan club.
The report further goes on to state that the fee will be paid in four instalments which means that the Reds will receive £4.4m every time the Brazilian reaches a 25-match milestone.
Coutinho reached the first instalment when he featured for Barcelona against Real Valladolid at the end of August, meaning the Merseyside outfit are due to make an additional £13.2m in appearance bonuses.
The second clause included in the sale deal was related to the Champions League. The Reds pocketed £4.4m when Barcelona qualified for Europe last season.
They are now set to earn the same amount again should the Catalan club finish in the top four, something which can be taken for granted in La Liga.
The third and final clause that can help Liverpool make more money from Barcelona is related to the Champions League. If Barcelona end up winning the UEFA Champions League this season, they will have to pay another £4.4m to Liverpool.
