The 30-year-old started his West Ham career by shipping 10 goals in three games, but the 30-year-old has now kept four clean sheets in his last five outings for club and country.
The former Newcastle and Liverpool man has nine England caps to his name and knows staying fit is imperative if he is to add to that tally this season and force himself into the squad for Russian Federation 2018.
"I think they will find it hard to get all three points at Burnley, but a point, preferably with a clean sheet would show that they have a little more resolve than they displayed in the early weeks of the season".
"They don't score too many goals, but they are tight at the back and know how to defend a lead once they get their noses in front".
"I have a feeling - or he is hiding it - that he doesn't give a. he puts himself above that situation", Bilic added. I am fully confident of my ability. I am feeling a lot sharper than I did at the beginning of the season, getting back fit.
"I watched the game against Slovenia and he was man of the match. In training, I feel a lot sharper, not 100 per cent yet but I am getting there".
Obiang says the Hammers' squad not on global duty were put through their paces over the two-week domestic break as Slaven Bilic's side aim to record back-to-back wins following the victory over Swansea last month.
