I don't confess to know an awful lot about Bolanos, but judging by his stats he seems to have a much better pedigree than Rodriguez.
Only one person's opinion, but just seen a tweet from an Ecuador fan stating that Bolanos is the best player they have, better than Enner Valencia who has looked ok at West Ham.
Nothing to lose really like I say, 5 million quid is nothing these days.
Depends how it's spent.
