The Southampton man is in fine form and Courtois believes his nation will have to pay him special attention when the sides meet in their second games of Euro 2016
Belgium goalkeeper Thibaut Courtois says Shane Long is at the same level as Romelu Lukaku and has urged his team-mates to keep the Republic of Ireland striker quiet on Saturday.
A surprise 2-0 defeat to Italy on matchday one has left Marc Wilmots' side needing a favourable result against Ireland in Bordeaux to keep qualification for the Euro 2016 knockout stages firmly in their own hands.
Long scored 13 times in an impressive season for Southampton and is expected to lead the line for Martin O'Neill's side when they take on Belgium, having played the full 90 minutes of the 1-1 draw with Sweden.
