Timo Werner's first goal in 15 Premier League games helped send Chelsea back into the top four with a 2-0 victory over Newcastle United on Monday. Werner's last Premier League goal had come on Nov. 7 after which he suffered a run of bad luck and bad finishing which visibly hurt his confidence. "I think for a striker it is much harder when you come into the situation and you don't have chances," Werner told broadcaster Sky Sports. "I had in the past a lot of chances and I missed them and also today my team brought me a lot of situations where I can score and it is important to keep going like today." A fourth straight league win since Thomas Tuchel replaced the fired Frank Lampard lifted Chelsea back into the fourth Champions League place.Tuchel gave out-of-favour goalkeeper Kepa Arrizabalaga his first league start since mid-October after his erratic form led to his replacement by Edouard Mendy. While Chelsea is accustomed to playing in Europe's elite competition, West Ham has never qualified. But the east London club is only behind Chelsea in fifth place due to an inferior goal difference after beating Sheffield United 3-0 despite having its only recognized striker, Michail Antonio, out injured.
