In my opinion, installing new manager at Stamford Bridge is not a good conclusion. As far as I concern, Chelsea performance was became quite dissappointing after Mourinho and Steve Clarke left.
Ancelotti 1st season was superb when he won back Premier League trophy to Stamford Bridge but he was sacked on his 2nd season due to inconsistent performance even though Chelsea finished second behind arch rival and champion Manchester United.
And now, Andre Villas-Boas, who won UEFA Cup 2010/11 with Porto came with the same mission. To win and bring back trophy to Chelsea. Some thing that everyone in Chelsea shirt really wish for.
However, sacking AVB will be a big mistake. Abramovic should given AVB gap and space for him to breathe.
For me, it is simple. Abramovic should invest in new players. Chelsea defending is questioning every week. Week in week out, Chelsea hardly get a clean sheet compared to Mourinho era. Departure of Carvalho seem like given a huge empty space at Chelsea defence. Arrival of David Luiz yet to give a huge impact. In fact, he been criticise by Man United legends, Gary Neville to see him like he plays a Play Station.
Offensive side, Chelsea lack of finishing power. GBP 50 million striker, Fernando Torres is inconsistent. For me, AVB should bring more players like Gerrard, Silva, Ash Young or Fabregas into the squad. Torres is a natural striker. Players like this love to score but he cant created chance for himself or anyone. They need a good supply ball from midfield to score.
Lastly, AVB should bring his magic back to Chelsea. Partnering Drogba and Torres is not a good example. Sturridge is quite fancy and love to score but not to create change to teammate. They need 3-4 players like Mata in the team.
