They have IRIS-T and SAMP/T, the latter being somewhat comparable to the Patriot. Beside American made aircrafts there are also locally produced ones. I would be more worried by the lack of a proper equivalent of AWACS.
In general though issue is not quality (at least compared to Russia) but quantity. Also if I was an European country I would be worried about the usability of any advanced weapon bought from our American friends: I wouldn't be surprised if, in case of confrontation between Europe and Russia, the guy in the Oval Office decided to block sales of spare parts in order to force war mongering Europeans to come to an agreement with peace-seeking Putin, or if his plutocratic friend decided to completely axe the project because "it sucks and drones are better"
