'Maresca's biggest positive'published at 15:07 19 August

The cliche of a player returning from injury being like a new signing is particularly applicable to Romeo Lavia.
Of course, Chelsea don't need anyone to feel like a new signing - they have enough who actually are - but Lavia played just 32 minutes for the Blues last season because of ankle and hamstring issues following his move from Southampton for an initial £53m.
After a full pre-season in which he was the only Chelsea player to start all six games, the 20-year-old midfielder started against former club Manchester City on Sunday and put in a performance described as "outstanding" by former Liverpool midfielder Danny Murphy on Match of the Day 2.
To play with such confidence, positional maturity, composure on the ball and defensive awareness in the Premier League would be impressive for anyone, let alone for a young man whose last competitive start came 15 months ago and who was making his first start for a club indisputably in transition.
Lavia looked far more comfortable within new manager Enzo Maresca's system than Enzo Fernandez did - a man who cost more than double his fee - and was fearless against a City midfield containing experienced, world-class talents Kevin de Bruyne, Mateo Kovacic and Bernado Silva.
The difficulty will come in Maresca's challenge of finding his most effective midfield, both in terms of structure and personnel.
Much has been made of Chelsea's bloated squad and the prices paid for Moises Caicedo and Fernandez, as well as new addition Kiernan Dewsbury-Hall's history with Maresca at Leicester City, make them challenging candidates to not start regularly.
What elevates the Belgium international is his potential to be truly elite both creatively and defensively. Some of his passing against City was exemplary and he shares Caicedo's athleticism and tenacity in the tackle.
In his analysis, Murphy said Lavia was the Blues' "biggest positive" and that "Chelsea fans will enjoy watching him evolve in the middle of the park".
If he continues in this vein, keeps himself fit and proves himself a worthy starter amid Maresca's bounty of options, this could well be a breakthrough campaign for him in west London.
