Because that was the official fee that was paid. Where did the above poster get 20million from?! So far Lukaku has cost us 10.7 million. Yes there are add ons but those could be paid at any time and I'm not sure what they are. For instance Sturridge until recently only cost us 5.5 million. But in November, after making his England appearance, over 2 years after he arrived, that fee is now 6.5 million. The fee when we first bought him was just 3.5 million (we paid them 500'000 for each 10 first team appearances upto 40). So currently, Lukaku has cost this club 10.7 million. Piazon cost about 8 million with an extra 1 million paid to Piazon and his agent - I don't see anyone talking about him being a bad buy despite he's worse for te reserves than Lukaku.
