Frank Lampard has admitted his relationship with Chelsea manager Andre Villas-Boas has "not been ideal”.But, after captaining the Blues to a 3-0 win over Bolton on Saturday, he stressed his commitment to the club.Asked about Villas-Boas, Lampard said: "I think, from the outside, you can probably see that it’s not been ideal but the important thing is not to focus on individual relationships too much."It can only be negative and people do like to play on negatives.”Although Villas-Boas praised Lampard after the Bolton win, he said his display does not assure him of a place in the team.The 33-year-old midfielder was dropped for the last two matches, including the midweek Champions League defeat by Napoli.But he returned to lead the side against Bolton - and scored his 150th Premier League goal.
