While it was a fascinating encounter for the neutrals, last night's 3-3 draw with Roma will have left Antonio Conte concerned. Chelsea struggled to truly impose themselves on the opposition at Stamford Bridge and although Roma produced some truly stunning goals, their defence was carved open far too easily.

The Blues host Watford on Saturday and while it should be a routine win on paper, Marco Silva's side have started the new season in good form, rising to fourth in the Premier League table and scoring the joint-most goals of any team outside the top three. They'll certainly fancy their chances of breaching Chelsea's defensive ranks as well.

That being said, there was one obvious positive for the west Londoners to take from last night's six-goal thriller - the superlative form of talismanic attacker Eden Hazard.

After starting the season on the sidlines through injury, the Belgium international has struggled to get going in the Premier League, yet to score or assist in 212 minutes thus far.

But Hazard showed his quality in the impressive 2-1 win over Atletico Madrid last month and it was a similar case in his latest Champions League outing, twice finding the net against Roma while ranking first throughout the Chelsea team for chances created and successful dribbles.

If the 80-cap playmaker can carry that form over to the English top flight, Chelsea will fancy their chances of beating any opposition regardless of how open their defence currently is. But there's no guarantee Hazard will be as effective against Watford and the Blues simply must improve at the back if they're to keep pace with Manchester City and Manchester United.
