That is why they are here.<br /><br />"We never rely on just two players. We rely on the whole team and the people on the bench.<br /><br />"We can see the qualities of the players and we can do even more than what we did last year, if we put our mind to it and be determined to work harder,'' the Nigeria international told reporters.<br /><br />Celtic are likely to trade tackles with Swedish champions Elfsborg in the third qualifying round of the Champions League following their 3 - 0 first leg away victory over Cliftonville.<br />
