Arsenal may have seen their lead at the top of the Premier League standings cut to just two points by the time they welcome London rivals Chelsea to the Emirates Stadium on Sunday.The Gunners have led the way since early October, but they have been coming under increasing pressure from Manchester City over recent weeks, with the Citizens travelling to Leeds for Saturday’s evening kick-off.Chelsea are also in need of the points as the battle to secure Champions League football for next season intensifies. The Blues head into the weekend fifth following disappointing draws in their last two league games against Leeds and Burnley.GET UP TO £30 WHEN YOU BET ON THE FOOTBALL WITH talkSPORT BETArsenal to win, both teams to score, Gyokeres to score and Chelsea most cards – was 31/4 now 9/1Leg one: Arsenal to winThe pressure appeared to be mounting on Arsenal following a run of just two wins in seven league games prior to last weekend’s north London derby, but that 4-1 thrashing of Spurs is likely to have settled some of those nerves.Mikel Arteta’s side should certainly be confident of overcoming Chelsea, as they are unbeaten in the last 10 meetings between the two sides across all competitions and have only lost one of the last 15 head-to-heads.The Gunners beat the Blues home and away in the EFL Cup semi-finals just last month and their recent record in London derbies cannot be overlooked, as they have lost just one of their last 25 Premier League games against fellow teams from the capital.With Chelsea having dropped points in their last two games against Leeds and Burnley, Liam Rosenior’s honeymoon period in the Stamford Bridge hotseat could well be over and the league leaders can capitalise on that by picking up all three points.Leg two: Both teams to scoreArsenal built much of their early-season success on a strong defence, conceding just three goals across their opening 10 league games, but that rearguard has been penetrated with much more regularity over recent weeks.The Gunners have conceded in 12 of their last 18 top-flight games, including each of their last three, and they will be facing a Chelsea side who have only failed to score in two of their previous 41 fixtures.Both teams to score has been a winning bet in each of Chelsea’s last five league games and that trend can continue in north London.Leg three: Viktor Gyokeres to score anytimeViktor Gyokeres had arguably his best game in an Arsenal shirt during last week’s north London derby, grabbing a brace to take his tally for the season in the Premier League to 10, while it is 15 overall for the Sweden international since his summer arrival from Sporting CP.There has been plenty of scrutiny surrounding Gyokeres since he pitched up at the Emirates, but with five goals across his last five Premier League games, he appears to be finding his feet.The 27-year-old also has previous against Chelsea, grabbing a goal and an assist in the first leg of last month’s EFL Cup semi-final tie.Leg four: Most cards: ChelseaDiscipline, or a lack of it, has been a problem for Chelsea this season, as they have picked up a league-high six red cards (seven if you include the one handed to former boss Enzo Maresca), the latest of which came against Burnley last weekend.Only two teams – Spurs and Brighton – have received more yellows than the Blues total of 60, while Arsenal’s tally of 38 is among the lowest in the division and they are yet to have a player sent off.In November’s reverse meeting at Stamford Bridge the hosts had Moises Caicedo dismissed and, in a game where they are expected to be on the backfoot for large spells, the Blues could rack up plenty of cards once again.GET UP TO £30 WHEN YOU BET ON THE FOOTBALL WITH talkSPORT BETOdds correct at time of publish and subject to change*18+ New customers only.
