This is a match which will determine who finishes first and second in the group and both sides are expected to play strong sides for this, Chelsea games have gone from a pretty wild attacking ones to a low scoring games thanks mainly to their defence, 6 of the last 8 matches they have played since these sides drew 0-0 saw Chelsea keep a clean sheet, Sevilla are a decent side at the back as well and have conceded only 3 goals in their 4 group games so far and I think we will see another close game between these sides and I believe the under 2.5 goals is a bet.
