The Costa Rican international signed for Arsenal in the summer of 2011, despite initially failing to obtain a work permit. And, as a result of permit issues, the 22-year-old spent the first three years of his Arsenal career out on loan with Lorient, Real Betis and then Greek champions Olympiakos.
It was his time in Greece which allowed Campbell to develop, scoring in a Champions League clash against Manchester United and winning a place in Costa Rica's 2014 World Cup squad.
His fabulous exploits in Brazil over the summer persuaded Arsenal boss Arsene Wenger to bring him back to the Emirates, a highlight of Campbell’s year.
'After Brazil came my third greatest moment of 2014; the opportunity to play for Arsenal, the club which trusted me and which I began to admire', he wrote.
'I worked hard in Lorient, Betis and Olympiakos for this challenge. I will never stop fighting for the shirt – the number 28 which today I defend to the death and will keep on fighting for day by day'.
Despite his impressive campaign at the World Cup, Campbell has seen his opportunities limited at the Emirates stadium, playing just 39 minutes of Premier League action all season.
Still, with time on his side and an excellent attitude and dedication to work for his team, the former Saprissa ace clearly hopes he has a bright future in North London.
Here are Campbell’s top four moments from 2014:
1. The moment he found out he was to become a father.
2. Representing Costa Rica at the World Cup, and his goal against Uruguay in a famous 3-1 victory.
3. Having the opportunity to play for Arsenal, three years after initially signing for the club.
4. The development of his website, for the fans and fellow sportsman who are proud to hail from Costa Rica.
