West Ham United will carry a slender lead of one goal into their second leg of the second round of Europa League qualifying against Maltese club Birkirkara FC.
The Hammers edged their rivals 1-0 at Upton Park on Thursday night thanks to a late goal from defender James Tomkins and manager Slaven Bilic is aware that the job is far from complete.
Bilic said: "It is not job done, of course. They will probably play the same way in Malta, and will wait again for some long ball, some mistake or counter-attack, but we are quite confident.
"We still have respect for the stage we are playing on and our opponents. We have a very busy schedule because we did not know were going to play in Europe.
"I am not saying it is going to be the same squad in Malta, but it is the game which we will try to put the best team."
West Ham head to Malta for the return bout in Birkirkara next Thursday.
