He wasn't relegated in 2016/17 with Las Palmas when he came over on loan in January. And this season he was out injured for most of the first half of the season but Las Palmas was just a mess so I doubt even Messi could save them from relegation.
He was actually playing good for Gijon in 15/16 season but again as a team they were just not good enough to stay up.
I have wrote my rule a lot of times: if too many coaches in a row don't count on a player, there is usually a very strong reason for it.
The next Messi Halilovic was allowed to leave Barcelona, then in Gijon Abelardo benched him at the end of a season, in Hamburg, Germans weren't happy with his workrate, in Las Palmas "the team was in mess", in Croatian NT team, he isn't nowhere close to an NT team for several coaches in a row.
3-4 years ago while he was here, I was annoyed with posts how he is a future starter because he never had a mental potential and his technical game was a one trick pony game with nice dribbles which sometimes remind on Messi.
Basically, reminding on Messi while running was his biggest footballing skill.
But he is highly ineffective player at the end of a day and a team often plays better without him on a field.
Anyway, before I somewhat hated this kid due to crazy hype from our forum, but lately I am sad about him.
Not only that he will never make it a big club, but I am unsure whether he will ever be able to stay in any club for more than 1 season without being loaned/sold/released.
Visually, he looks as a shiny and dangerous player, but obviously, when coaches get to know him and when they were able to analyze his actual impact on a play over 20-30 matches, every single coach gives up on him and sells him to a new club.
I hope that he will be able to improve mentally, to be more effective on a field and have at least some semi-decent professional career.
He will probably have a career like Bojan Krkic.
