Neymar, 25, only joined PSG in the summer, when the French side paid £200million to activate the release clause in his Barcelona contract.
Ramos told Cadena Ser: #8220;I like to have the best and it#8217;s clear Neymar is one of them.
#8220;He knows what he#8217;s doing. He#8217;s a great player and he#8217;ll always be welcome at Real Madrid.#8221;
#8220;Maybe it was easier for him to go to PSG, instead of directly to Real Madrid. They are personal decisions, you never know what can happen because football goes around a lot.
#8220;I already have the door open for him if he wants to come. I also have a good relationship with him.#8221;
Los Blancos see Neymar as a long-term replacement for Cristiano Ronaldo #8211; who turns 33 in February and is almost exclusively being used as a centre-forward by Zinedine Zidane.
