Chelsea are in excellent form at the moment. Having won the Champions League last season, they have built on that success under Thomas Tuchel this season.They are currently top of the Premier League, and are among the favourites to win the league this time. They have quality in every position, which means some players have not had too many chances to display their worth.With quality in every position, manager Tuchel has a welcome headache. Not all players will be happy with his decisions, though. On that note, here's a look at the five players who deserve more opportunities at Chelsea.#5 Saul NiguezChelsea vs Aston Villa - Premier LeagueSaul Niguez's career has stagnated in recent years. From being a young superstar at Atletico Madrid, he is now warming the bench at Chelsea.Last season, he only had limited impact for the La Liga giants as they won the league title. The Spain international joined Chelsea on a loan deal this summer amid much fanfare. His technical qualities and defensive prowess seemingly made him an ideal addition to Thomas Tuchel's side.Saúl Ñiguez@saulniguez👋🏽 @ChelseaFC7:26 PM · Oct 29, 2021390532298👋🏽 @ChelseaFC https://t.co/DRr4fxHDnXHowever, he has struggled at Chelsea. A poor debut against Aston Villa did not help his cause. He has also found it difficult to oust stars like Jorginho, N'Golo Kante and Mateo Kovacic from the first XI.The 26-year-old has only made two Premier League appearances, accumulating a grand total of 48 minutes. The sample size is too small right now to make a judgement. But right now it seems unlikely Chelsea will make his deal permanent.#4 Ruben Loftus-CheekMalmo FF vs Chelsea FC: Group H - UEFA Champions LeagueRuben Loftus-Cheek was once regarded as the future of the Chelsea midfield. Injuries have hampered his development, though.A product of Chelsea's famed youth academy, Loftus-Cheek displayed his talent during loan spells with Crystal Palace and Fulham. Since then, he has produced some good performances for Chelsea, but consistent injury problems have proved to be a big problem. Loftus-Cheek has now been overtaken by bigger names at the club.Ruben Loftus-Cheek@RLCHard fought win!

He has made two starts in the Premier League, which is evident that manager Tuchel rates him well. The 25-year-old has what it takes to become a regular fixture in Chelsea's midfield.You may also like: 5 highest-paid right-backs in the world right now.
