I think Chelsea set a selling price too high for Lukaku which in the end was very difficult for Inter to accept. Lukaku is still good, but I don't think his value is higher than 30 million euros, but Chelsea want Inter to pay more. Loan options are being discussed, but it seems Chelsea just want to sell rather than put him on loan again.
Inter have so far not looked like they are going to force Lukaku's transfer at the value asked by Chelsea, that's because Inter seem to want to save a lot of money for other plans. Chelsea had to make a tough decision about Lukaku but I think 30 million euros is a good value for a 30 year old striker.
Ofcourse Inter Milan will be reluctant to buy the Chelsea man who is past his prime years for £30 million. Such amount for a 30 year old isn’t common, the fact that Chelsea prefer to sell him permanently rather than accepting a loan will make it even difficult to strike a deal. Somehow they will have to find a way around the transfer fee, Chelsea will have to reduce the fee for Inter Milan to get the player this summer.
Lukaku might be in his 30s but when it comes to delivering performance he surely doesn't disappoint and I think inter will be well aware of this as lukaku was a prominent figure in their achievement during their last season performance although they didn't secure the title but reaching the finals was a major achievement for them and making a permanent deal with chelsea at £30 million for lukaku won't be a wrong move if they know his Worth.
