Jonas Gutierrez has signalled his readiness to step into the depths of a crisis which is threatening to end Newcastle 's season with a whimper . The 31-year-old Argentinian has been used as a substitute in the Magpies ' last two games after his return to the squad following a successful battle against testicular cancer . However , as head coach John Carver prepares for Saturday 's Barclays Premier League fixture against Arsenal at St James ' Park with suspension and injury severely limiting his options , Gutierrez is offering his services in whatever role he is needed . Jonas Gutierrez posted this picture to his official Instagram account on Wednesday morning . The Newcastle midfielder made his second substitute appearance in the defeat by Everton on Sunday . He told the Journal : 'Three years ago when we finished fifth , I played in many positions . I was playing in different positions because we had problems with injuries . ' I 'm here to help . I work hard and I want to enjoy . Always , I have to do the best for the team . 'We have to finish in the top 10 . We do n't have any excuses . We have hard games up to the finish of the season , but we have to take points and finish in the top 10 . ' A winger by trade , Gutierrez played as a full-back for his country at the 2010 World Cup finals , and that ability could come in useful during the remaining weeks of the season . Skipper and close friend Fabricio Coloccini will miss the next three games after failing in a bid to have the red card he received at Everton on Sunday overturned on appeal , and with Steven Taylor and Paul Dummett out for the rest of the season through injury , Mike Williamson is the club 's only recognised senior central defender . Gutierrez , who recently returned to first team after beating testicular cancer , is ready to step in where needed . Gutierrez and his Newcastle team-mates applaud the travelling fans after the 3-0 defeat by the Toffees . VIDEO Bringing Jonas on was n't sentimental - Carver . That could mean a move inside for right-back Daryl Janmaat against the Gunners , and with the Dutchman currently the club 's only fit specialist full-back , Gutierrez could be required to slot into a re-shaped back four , as Ryan Taylor has done in recent weeks , although Carver will hope to have Massadio Haidara ready for the weekend . Newcastle have won only one of their last six games and scored just three goals in the process , and with leading marksman Papiss Cisse just one match into his seven-game ban , their hopes of a top-10 finish appear to be receding . Gutierrez said : 'We do n't have enough players at the moment . Colo is banned for three games . But we have to keep together and work hard for the manager . 'The manager will tell us what we have to do . We have to do it right on the pitch . No excuses , we have to do it better . '
