Arsenal must win Chelsea this week

Today, top Premiership contention situation is intensified, while Arsenal is a "culprit." In the last few league games, the gunmen played poor; even to face the weaker Everton, they are still hard to get a win. Last 3:6 defeat to Manchester City, two consecutive losses, Arsenal’s points gap is getting smaller with other title rivals.
The reality is that the top four standings are Arsenal, Liverpool, Chelsea, Manchester City, but there are only 3 ponts between Arsenal and Manchester City. In other words, if the Blues lost to Arsenal in this field, while Liverpool and Manchester City successfully win, the Gunners will drop the fourth standings. This is a huge blow for them.
Thankfully, the game will be at home, while their opponent will be Mike Mussina led Chelsea--the former home winning rate of 75%, while the latter away winning rate of 37.5%.
Nearly five home league matches, Arsenal had 4 wins and 1 draw impressive record, including 4:1 victory over Norwich, 2-0 victory over Liverpool these convincing record. But in the recent two rounds of the league, Arsenal draw at home to Everton, away 6 balls lost to Manchester City. Their performance in tough games really makes people worried about them.
