Liverpool will actually win the Premier League trophy this season. Currently they are at the top and leading with 15 points, which is enough. There is not any team in the Premier League that can surpass them in points, so this season the Premier League trophy is for Liverpool. Obviously they cannot put more effort than before into the Premier League because that is their main target for now, and I know they will go towards it.
Yes, 15 points gap is enough to be confident at the top of the EPL table especially as Arsenal that is behind them are not consistent enough to become a threat to them anymore because there were several chances for Arsenal to close the gap when Liverpool drop some points back then, but the Arsenal were also affected by injuries which is the main reason they are still behind with 15 points difference. However, since Liverpool has now been eliminated in the Champions League, they will put more attention on winning the Premier League and I know they will do their best because we have less than then matches to go and I don’t think they will lose them all, so there is indeed no chance for Arsenal anymore.
