It's a good opportunity for Liverpool to get closer to City. The draw results when City meet shouthampton, at least made Liverpool cut the difference by 2 points. There is still 1 game left for liverpool (compared w/ City), if in this match Liverpool win again, then the difference in points will be closer to 51 for Liverpool, which means there is only 6 points gap. It makes sense that the competition for the title will be more interesting.
Klopp has been trying to play down the chance of Liverpool catching City, which I think is a good decision. Of course Liverpool have closed in a bit, and the gap looks more manageable now, but by saying that Liverpool shouldn't think about catching them, Klopp keeps all of the pressure on City, and no expectation on his own players. It's the obvious strategy, but managers don't always follow it.
