It's as easy as 3-4-3 for Antonio Conte's Chelsea
Silva would be a good fit for Everton
Five things we learned from the weekend
1 Return to old formation helps Chelsea
Antonio Conte's subtle switch from a 3-4-3 formation that won last season's Premier League title to a 3-5-2 this term has made Chelsea difficult to beat but the champions were back to their best as the coach reverted to a three-man forward line at Brighton.
Explaining the decision to field an extra midfielder, Conte told ESPN earlier in the campaign: "We are changing something to find a new balance, a new solidity, to have a good balance."
However, Eden Hazard and Alvaro Morata have been too isolated in recent weeks so it was good to see the brilliant Belgian combining so well with the returning Willian in the 4-0 success.
There may well be times when an extra midfielder is needed - against Barcelona for instance in next month's Champions League tie - but outside of matches against their fellow big-six teams Conte should be looking to field three forwards on a regular basis.
2 Everton should look for Silva's service
It was reported that Everton had a £10m bid for manager Marco Silva knocked back by Watford in November and it will be interesting to see whether the Merseysiders go back for the Portuguese following his sacking from Vicarage Road.
After all, he cannot have become a worse coach in just a couple of months and paying off Sam Allardyce will surely be cheaper than the hefty fee Everton were prepared to invest to get Silva in the first place.
What remains clear is Allardyce is having trouble at Goodison Park. Being dominated by Manchester United, Tottenham and Liverpool is one thing but even West Brom had far more attacking oomph about them in Saturday's 1-1 draw.
3 Lambert's arrival lifts Stoke
Positive touchline antics will only take a team so far but Stoke supporters were desperate for a lift and Paul Lambert provided the locals with something to cheer as his jack-in-the-box style celebrations went down a storm.
For too long Mark Hughes cut a sorry figure, moaning and blaming everyone bar himself for Stoke's slide down the Premier League table, but Saturday's deserved 2-0 win over Huddersfield was definitely a step in the right direction with the statistics showing City had sprinted more than in any other match this season.
Long-throw guru Moritz Bauer impressed on his home debut at right-back and the bet365 Stadium could be a difficult place to visit in the next few weeks as the Stokies look to turn it back into a bear pit.
4 Brentford are buzzing
It has long been said that Brentford are better than their league position suggested in the Sky Bet Championship and the Bees made it five wins in six league games with a 1-0 win at Reading on Saturday.
It's three clean sheets in four outings too with centre-back Chris Mepham continuing to impress, while Lasse Vibe's goal showed just how important his return to fitness has been for Dean Smith's men.
Brentford have won only four of the 18 matches Vibe has not started this season compared to eight victories in 14 when he has been available.
5 Bradford in need of reinforcements
Tony McMahon and Charlie Wyke continue to be linked with moves away from Valley Parade but Bradford's performance in Saturday's 3-1 loss to Bristol Rovers suggests they need to be looking to strengthen this month rather than losing influential performers.
The loss at Rovers, who had seven shots on target compared to Bradford's two, was City's fifth defeat in seven.
