From the get-go it looked as if Mikel Arteta knew exactly how Frank Lampard would set up his squad i.e. the Spaniard knew precisely how the Englishman wants his team to play, to attack and defend. Truth be told, Arteta has been in the managerial waters longer and Lampard has taken over a collection of players that much more experienced managers would not know what to do with – but that does not take off the impression that tonight’s London ‘Derby’ at the Emirates was all but a derby.Pickford saves the penalty after reading the notes on a water bottleArsenal won for the first time in over a month as they eased past a woeful Chelsea side to return to the top of the Premier League for the time being, as the hapless Blues suffered a 20th defeat of the season for the first time since 1987-88.Despite having seen their title quest falter badly in the last few weeks, the Gunners were buoyed by the prospect of a home game against a Chelsea team who had not won in the league since March. Arteta’s men made a trademark fast start, and after two early interventions from Blues goalkeeper Kepa Arrizabalaga, the Gunners, who had only failed to score in one of their 16 league games at the Emirates Stadium this season prior to this match, broke the deadlock early. Granit Xhaka’s low pass into the area picked out the unmarked Martin Odegaard on the edge of the box, whose first-time left-footed effort went in off the underside of the bar.YOU CAN WATCH ODEGAARD’S FIRST GOAL HERE.This undoubtedly gave Arteta’s side the early boost they needed, and they kicked on in ruthless fashion to leave a timid Chelsea side in their wake. Just after the half-hour mark, it was a case of déjà vu when Odegaard was once again found by Xhaka, and for a second time he swept past Arrizabalaga to double the lead with his 15th goal of a stellar season. Then, just three minutes later, the Blues’ misery was compounded when a ball into the area from Ben White wasn’t dealt with by the defence, and it eventually found its way to Gabriel Jesus, who powered home from a few yards to put Arsenal in dreamland at halftime.YOU CAN WATCH ODEGAARD’S FIRST GOAL HERE.YOU CAN WATCH JESUS’ GOAL HERE.The visitors knew the second half was a damage limitation exercise, as they seeked to restore some pride, but it could easily have got worse for them when Gabriel’s header was cleared off the line by Thiago Silva, before Xhaka’s shot was pushed around the post and Saka fired just wide from range. The one blot on a brilliant evening for the hosts came with 25 minutes remaining, when Noni Madueke collected a ball into the area before dinking over Aaron Ramsdale. Sensationally, that was just the second goal Chelsea have scored since Lampard’s return as interim manager in March, laying bare their attacking problems that have plagued them all season long.YOU CAN WATCH MADUEKE’S GOAL HERE.Chelsea did improve slightly in the closing stages, although in truth they could not have been much worse, as Arteta’s men eased to a victory which helps to keep the pressure on title rivals Manchester City, with a thrilling title race likely to go down to the wire. Chelsea’s ambitions, meanwhile, are limited to trying to avoid a first bottom-half finish since 1996 after suffering a sixth successive loss under Lampard.PREMIER LEAGUE – MATCHDAY 34Saturday Crystal Palace – West Ham 4-3 (3-2)/Ayew 15, Zaha 20, Schlupp 30, Eze 66 pen – Soucek 9, Antonio 35, Aguerd 72/Brentford – Nott.
