LONDON, May 21 (Reuters) - European stock futures pointed to a weaker open on Tuesday, with concerns the U.S. Federal Reserve might begin slowing its bond purchases later in the year prompting investors to take profits from a rally to five-year highs.
At 0602 GMT, futures for Euro STOXX 50 (Zurich: ^STOXX50E - news) , UK's FTSE 100, Germany's DAX (Xetra: ^GDAXI - news) and France's CAC were 0.1 to 0.3 percent lower.
