There was always going to be criticism aimed at Southgate given England's strength and depth.We look at the 5 biggest stars left out of England's provisional squad for Euro 2020.#5 Ezri Konsa (Aston Villa)Crystal Palace v Aston Villa - Premier LeagueAston Villa enjoyed a good first-half of the 2020/21 season, with Dean Smith's men tailing off as the season progressed.But two players stood out for Aston Villa throughout the campaign. Jack Grealish and centre-back Ezri Konsa were the star performers for the Villans, and Konsa was one of the best centre-backs in the league this season. The 23-year old, who joined Aston Villa from Brentford for £12 million in 2019, formed a strong defensive partnership with Tyrone Mings for his club. While Mings has been named in the Euro 2020 provisional squad, Konsa misses out.⛔ Ezri Konsa has blocked more shots than any other player in Europe's top 5 leagues this season (46) pic.twitter.com/RMO5V02Gkz— WhoScored.com (@WhoScored) May 21, 2021Konsa can operate as a right-back if needed as well, and made 36 Premier League appearances for Aston Villa this season, scoring two goals. The former Charlton Athletic man has been linked with Tottenham Hotspur and Liverpool recently and could have been a good backup centre-back for England at Euro 2020.#4 Danny Ings (Southampton)Southampton v Manchester City - Premier LeagueDanny Ings has been Southampton's star player since joining the club in 2018 from Liverpool.The striker has been in excellent form for the Saints since his arrival. Last season Ings scored 22 league goals for Southampton and has fitted in perfectly at the club under the management of Ralph Hasenhuttl. He would surely have been in the squad for Euro 2020 had the tournament been held last year. This season Ings made 29 Premier League appearances, scoring 12 goals and providing four assists for a struggling Southampton side.BREAKING: England confirm a provisional 33-man squad for Euro 2020 🏴󠁧󠁢󠁥󠁮󠁧󠁿Trent Alexander-Arnold is included ✅Uncapped defenders Ben White and Ben Godfrey also get the nod 👏Eric Dier and Danny Ings are among those left out ❌ pic.twitter.com/FmuBp2mwsv— Goal (@goal) May 25, 2021The 28-year old has been linked with a plethora of top clubs as a result of his performances.
