It's a crucial London derby at the Emirates on Saturday night and Paul Higham thinks Chelsea's more solid foundation can put Arsenal in even more trouble in their top four bid.

The flying form of Manchester United has put both of these sides under pressure ahead of this latest London derby where both sides have big questions to answer after recent results have undermined positive starts to the campaign.
Arsenal's lengthy unbeaten run has fallen apart with just two wins in their last six as their defensive ineptitude has finally caught up with them - but the question is can Chelsea exploit that with basically just Eden Hazard as their main goal threat?
The Gunners would be wise to try and stay tight and compact at the back and let the likes of Alexandre Lacazette and Pierre-Emerick Aubameyang do all the damage going forward, but Unai Emery's options at the back haven't really shown they are capable of such a game plan.
If they play as they have been, Hazard will have plenty of space to do damage and he's been lethal this season when afford acres of turf to run into.
Arsenal's own attacking options look much fuller than Chelsea's and the Blues have looked vulnerable themselves at times, never more so than in the first meeting between the two which they won 3-2 but could have conceded five on another day.
Chelsea are favourites as they seem more likely to be able to conjure up enough defensive competence to take the points - on what we've seen so far they look a bit too strong for the hosts to handle.
Prediction: Arsenal 1-2 Chelsea (Sky Bet odds: 17/2)
There could be plenty of goals in this one given Arsenal's usual way of playing, but this is a big game and Emery is well aware of it so they'll be tasked with producing a much more solid performance, which they should do, but it looks like they'll be just short.
Best bet: Chelsea to win at 13/10
Chelsea have not been great but they've been good enough to sit six points above the Gunners in the table, they've also mainly struggled to break defensive teams down and this Arsenal side have produced fewer clean sheets than anyone bar Fulham in the Premier League. It's a decent enough price to be interested in.
Stats: Granit Xhaka to be booked at 7/4
The Swiss midfielder is a walking yellow card in these big games - he's been booked ten times in 29 appearances for club and country this season but more importantly he's been shown the yellow card in five games out of six against the top six. That's some level of consistency.
