Don't know how I feel about Getafe as his destination with their obvious historically connections with Madrid though they seemed to move away from that a bit.
I think Bordalas is a very good coach and they've already signed Jaime Mata and Sergi Guardiola (yes, the one who was our player for a few hours
years ago) who have scored more than 50 goals combined in Segunda last season and according to rumours they are after some other good players (watch out for Gonzalo Melero from Huesca if they can get him) and while it's unlikely they'll repeat last season and be able to compete for European spots they seem more like a solid midtable team than relegation candidates to me right now but of course a lot can still change until the end of transfer window.
I would prefer Arnaiz going to a team who plays more offensive to make the most out of his potential but if he'll get regular playing time in his first La Liga experience this loan could work out as well for him. Age is probably limiting his upside and will most likely prevent him to make it back to our first team as a squad player in a year but if he'll stay healthy and have a good season it could raise his value and generate interest from better teams so we can sell him next year.
Lol, Sport is now reporting Barça has denied Arnaiz to Getafe is a done deal and people inside the club were surprised about Angel Torres's statement. They are also saying other clubs are better positioned than Getafe to get him. Could be just their usual BS but if true Torres is even worse than Pep Segura.
