This is the fact, even Chelsea since the beginning of the season has been having good ball possession and lots of chances to score But thank God they where able to get a clean sheet and a win.
Of course it's true, Chelsea have dominated possession in almost all the games they've played so far, except today in the win against Brighton. On average, Chelsea has 65% or 66% possession in their last 8 matches, but Pochettino still failed to win many matches. I think this is one of the pluses for Pochettino that many people have overlooked, but it's useless because the result of the match is much more important than a high percentage of ball possession.
Chelsea coach Pochettino is looking to apply new match tactics. In every match we saw Chelsea looking to control the match with possession of the ball. But in the end they failed. Chelsea's attack is very weak. The team failed to control the match by only possessing the ball. Pochettino should definitely think of a different strategy. Chelsea did not succeed in this strategy. If Pochettino wants to keep this strategy intact then he will definitely need to bring changes to the squad. However, Chelsea's chances of winning against Fulham seem slim to me. I don't think coach Pochettino will be able to improve the situation of the team so quickly.
