  1. let the statements 7,8 be true:then
    1.The statement 2 cannot be true since the remaining 6 statements(i.e leaving 7,8) should be lies..which is not possible
    2.statement 6 is also lie bcoz if that is true there will be atleast 1 statement that contradicts this statement(as there are 4 possibilities leaving statements 2,6,7,8)
    3.statements 3,4 are also lies bcoz if it is true then statements 3,4 will be true and the total no.of lies is only 4(1,2,5,6)
    4.statement 5 is also lies bcoz if 4 are lies then statement 1 should also be a lie which contradicts this statement
    5.so there are only 5 lies in total so..statement 1 is also a lie
    6.So,now we got all lies...so statements 7,8 are true is a contradiction..so statements 7,8 are false..so 7 is Lampard and 8 is Torres :)

    This can be proven in the other way also taking statements 7,8 are lies
    If 7,8 are lies then
    1.statement 6 is also alie bcoz there will be atleast 4 statements which will contradict this statement(by removing 7,8,3 and other 1 lie)
    2.now we have 3 lies..so statement 5 is also a lie bcoz there will be atleast 2 lie which contradicts this statement(removing 7,8,6,(3,4) or 2 or 1)
    3.statements 3,4 are also lies bcoz now we have 4 lies,if there are 5 lies then one of the 1,2 should be lie and the other is true which is not possible
    4.statement 2 is also lies bcoz now we have 6 lies..if statement 2 is true then statement 1 will be lies and we'll have 7 lies so the statement 2 is lies
    5.now that we have 7 lies..statement 1 is true
    So,there is a true statement satisfying all the possibilities when statements 7,8 are lies..so 7 is Lampard and 8 is Torres..cheers!! :D :D
