Jamie Carragher has hailed the impact of Chelsea goalkeeper Thibaut Courtois , who put a first-half error behind him to help the Blues to victory against Hull City . Chelsea went 2-0 up through Eden Hazard and Diego Costa , but Hull pulled level after Courtois gifted possession to Abel Hernandez just before the half-hour mark . And Carragher , speaking on Sky Sports after the game , thinks that despite his error , there are few goalkeepers as good as the Chelsea man . Thibaut Courtois made an error in the first half to gift Hull their equalising goal against Chelsea . Courtois gave away possession under pressure from Gaston Ramirez to allow Abel Hernandez to score . 'He had a bit of a mix-up in the first half , ' the Sportsmail pundit said . 'He 's a world class goalkeeper to keep Petr Cech out and what he did last year for Atletico Madrid , getting to the Champions League final . 'He 's a fantastic keeper and he 's going to be one of the world 's best for a decade or so . ' Speaking alongside Carragher was former Arsenal striker Thierry Henry , who was in agreement at Courtois ' excellent game despite the high-profile error . 'Before the mistake , he made a couple of saves that kept Chelsea in the game , ' Henry noted . 'But it 's not about the mistake , it 's about how you respond , and he responded well in the second half . ' Chelsea 's 3-2 win took them back to winning ways after a draw against Southampton last time out , and restored their six-point gap ahead of Manchester City at the top of the Premier League . Jamie Carragher ( left ) and Thierry Henry hailed Courtois ' impact in the second half to save Chelsea . Courtois made a string of saves , including three in quick succession , to help Jose Mourinho 's side to victory . Their win at Hull was far from convincing , but according to Henry , getting three points in the manner Chelsea did is a mark of their winning mentality . 'Big teams will do that to you , ' he said . 'Three attempts on target , three goals . It sounds simple , but that 's what Chelsea are about . 'Hull were unlucky in the second half on a couple of occasions , but that 's what a big team does to you . They come here , they do n't really perform well , they find themselves in a difficult situation , and they managed . ' One negative for Mourinho will be the injury to Diego Costa , which forced him off with 15 minutes to play holding his hamstring . Carragher thinks Courtois ( pictured ) will be one of the world 's best goalkeepers for a decade . Carragher and Henry also believe that Chelsea 's title hopes will remain successful , even without Diego Costa . Chelsea 's strike force is such that Costa 's absence is unlikely to be a devastating blow , and the presence of Remy in the latter stages actually forced a winner for the league leaders . 'It looks like a hamstring injury and we know his history from the Champions League final , ' Carragher said of Costa . 'If it is a hamstring injury , if Remy has to come in , he 's come on there [ against Hull ] and he 's made a difference . 'He scored in the Manchester City game as well . He 's not what you 'd call top level , he has n't played that much , we know Jose just likes to play the same players . He 's not at Costa 's level , but he 's enough to go up front and take them to the title . 'They 've got that gap now , if they miss him for two or three games - depending on how bad the injury is - I think they 'll be fine . '
Chelsea went 2-0 up against Hull but were pegged back to 2-2 . Hull 's second goal came after a mistake by goalkeeper Thibaut Courtois . Jamie Carragher hailed Courtois ' the second half performance , to come back from the error and help Chelsea to victory . Diego Costa came off injured , but Carragher and Thierry Henry believe Chelsea have enough strength in depth to win the league .
