i would recommend using 1 defensive midfieder as a support deep lying playmaker, this really makes a difference to how a team plays with two deep midfielders and then 4 attackers.
you will normally want a support striker next to a Target man, I would recommend munian(support dlp) next to llorente as attacking target man. that's what I play, finished second first season.
mat hummels, if he hasn't been bought by Madrid (probably) yet or Benedict howedes.
I also rate Jefferson farfan as a winger, really consistent and hard working, won't cost much either.
