The race for the quarter-finals of the UEFA Champions League intensifies this week as the Round of 16 second-leg ties take centre stage across Europe. Sixteen clubs remain in contention, but only eight will advance to the next round of the Champions League tie. With first-leg results already on the board, the return fixtures on Tuesday and Wednesday promise high stakes and little margin for error. Tuesday’s action opens with Sporting CP hosting Bodo/Glimt in Lisbon. The Norwegian side carries a commanding 3-0 lead from the first leg, leaving Sporting with a mountain to climb at home. At Stamford Bridge, Chelsea FC face a daunting task against Paris Saint-Germain after a 5-2 defeat in Paris. The Blues must score freely while keeping things tight at the back if they are to turn the tie around. Over in Manchester, Manchester City welcome Real Madrid to the Etihad Stadium. Pep Guardiola’s side trails 3-0 from the first leg and needs a near-perfect performance to overturn the deficit against the Spanish giants. North London hosts another finely balanced tie as Arsenal take on Bayer Leverkusen at the Emirates Stadium. The 1-1 draw in Germany leaves the contest wide open, though Arsenal will look to make the home advantage count. Wednesday’s fixtures continue the drama. FC Barcelona meet Newcastle United FC at Camp Nou following a 1-1 draw at St James’ Park. Another tight affair is expected, with Barcelona holding a slight edge on home soil. Tottenham Hotspur FC face a steep climb against Atlético Madrid after a 5-2 loss in Spain. Spurs must deliver a standout display in front of their fans to keep their campaign alive. At Anfield, Liverpool host Galatasaray in one of the most finely poised ties. The Turkish side holds a narrow 1-0 lead, but Liverpool’s home record keeps the outcome uncertain. The final tie sees FC Bayern Munich in complete control against Atalanta BC after a dominant 6-1 win in Italy.
