Chelsea's season has been an up and down one to say the very least, and manager Mauro Sarri remains under pressure to deliver a top four place come the end of the season.

A good, solid win in midweek over Kiev has improved the mood further around Stamford Bridge, with the Blues looking to put together a run of form which can see them secure a Champions League spot ahead of the 19/20 campaign.

However, with Chelsea now under a transfer ban for the foreseeable future, keeping hold of their key men is going to more important than ever.

The likes of Eden Hazard are bound to be the main priority, but we here in the Tavern feel that the Blues keeping hold of fellow attacking midfielder Willian is going to be just as important.

The Brazilian is always a player who seems to deliver on the big stage when it matters, and this leads to plenty of admiring glances from some of the biggest clubs in world football.

Chelsea though need to ensure they keep hold of the former Shakhtar man, who showed his quality in the win over Kiev this week with a trademark free kick.

Willian has developed himself into one of the finest technical players in the Premier League, and a player who on his day, is capable of winning any game with a moment of magic.

While ever the club remain under any sort of embargo, it's imperative they keep hold of their best players, and Willian certainly falls into that category.
