That's the difference between Chelsea and Arsenal. Chelsea is competing for second place but Arsenal is chasing for the title. Liverpool will drop a point. Chelsea might not be able to keep up with their performance because they still have strong games ahead of them.
The title is actually beyond the reach of Chelsea that's why they prefer competing on the second position but arsenal on the other hand is too strong to want only the second position so the trophy is there motivation while Liverpool is on there better face now because there is no way I would say that arsenal will top the premier League when Liverpool has up to 7 point different from them and to make things more complicated for arsenal Liverpool will be having smooth wining from there premiere league matches they would be having from now because certainly they would win Everton, Full ham and so many others. However what if Liverpool win the premier League and also the champions League how would they be rate?.
