QPR defender Mauricio Isla is convinced his Chile international colleague Alexis Sanchez will become the best player in the world after a sensational start to his Arsenal career this season . Sanchez and Isla were this week included in a 20-man Chile squad to play a friendly against Brazil at the Emirates Stadium on March 29 , and also against Iran . Sanchez , who has scored 18 goals this season , has helped fire Arsenal to third in the Premier League table , where they sit just a point behind Manchester City . And Isla , who is on a season-long loan deal at Loftus Road from Juventus after impressing for Chile at last summer 's World Cup in Brazil , believes Sanchez has all the ingredients – and the temperament – to eclipse even Barcelona striker Lionel Messi and Real Madrid 's Cristiano Ronaldo as the best in the business . Arsenal 's Alexis Sanchez can become the best players in the world , according to Mauricio Isla . ' I have known him for ten years and I think Alexis has shown what he is made of , ' said Isla . 'He has always said that he wanted to be the best in the world and now he has arrived in a team where this can truly become a reality . 'He can build confidence and where they play for him and he transmits the confidence that his teammates give him but honestly , I am not at all surprised by the quality of Alexis as a player . ' I am proud to play alongside him for Chile , as I am proud to play alongside Arturo Vidal of Juventus and Claudio Bravo of Barcelona among others . I think together we are able to succeed and it would be fantastic for our country . Sanchez was one of Chile 's star men at the World Cup and will be a key man at the Copa America . 'Alexis Sanchez is a leader as are the other two . Of course , the team is a group but there are always role models in any team and I think these three in particular are fundamental to ours . 'There are always high quality players and these three are the pillars of our team and the rest of us must accompany them to achieve great things . 'Firstly Alexis Sanchez provides what I believe we lacked before which are his goals . 'It 's fantastic that he is scoring so much which fills him with confidence and joy and I hope he continues to keep scoring always more . 'If we were to talk about his characteristics , we could be here all day but for me , I love playing with a player who 's so bold , who is a fighter , runs for 90 minutes and always loves training . ' I have heard from many of his Arsenal teammates also that he never tires in training or on the pitch and this is fundamental for the team . ' QPR 's Mauricio Isla is proud to play for Chile alongside the likes of Sanchez and Arturo Vidal of Juventus . Also included in the squad is Barcelona goalkeeper Claudio Bravo , former Cardiff midfielder Gary Medel , Fiorentina 's David Pizarro , QPR 's Eduardo Vargas and Juventus midfielder Arturo Vidal . And Isla has issued a warning to Brazil boss Dunga to expect a serious test against fellow South Americans Chile at the Emirates Stadium . The friendly in North London will take on extra significance as Brazil secured a dramatic penalty shootout win against Chile to reach the last eight at the World Cup last summer and set up an all-South American quarter-final against Colombia . 'It 's a game that give brings up some pain , for everything that happened in the World Cup which was a beautiful game , I think as much for Brazil as it was for Chile , ' added Isla . 'The game played on for 120 minutes before going to penalties and sadly Brazil won but they really had to work for it . 'To play this game as a revenge match in a beautiful country , and beautiful city such as London , all Chileans will take interest and I hope it goes well . ' Brazil v Chile is on March 29 at 3pm at the Emirates Stadium in London . Tickets are on sale at arsenal.com/tickets .
