Having completed a sensational deal to sign former Barcelona legend Lionel Messi, Paris St-Germain will next look to sign Portugal forward Cristiano Ronaldo. But the 36-year-old Juventus star will not be heading to France now - a deal could be done in the summer of 2022 when he is a free agent, just like Messi was. Ronaldo could be a replacement for 22-year-old France striker Kylian Mbappe. Mbappe has been linked with Real Madrid for some time now and could be heading to Spain.
