Bayern Munich have signed James Rodriguez from Real Madrid on a two-year loan deal, the Bundesliga champions have announced.
Bayern, managed by former Real boss Carlo Ancelotti, will have the option to buy the Colombia international in 2019.
Ancelotti worked with Rodriguez during what was probably his most productive season at the Bernabeu - his debut campaign in 2014-15 - and he will hope to get the best out of the 25-year-old once more.
Rodriguez had fallen out of favour at the Bernabeu to such an extent that he was left out of their squad for the Champions League final in June.
Meanwhile, Douglas Costa is set to leave Bayern and sign for Juventus on a two-year loan deal as well.
Here's a look at the top 10 loan deals.
