He said: "Ten points is good but we've two very difficult games [left] and we're going to enjoy them. For Granada, every game at this level is something new to be savoured."Choose your Team of 2020
The 1988 European champions will hope to cool the newcomers' enthusiasm as they head to Spain, Roger Schmidt's side having come from 2-0 down to beat PAOK 3-2 last time out. "To be honest, the coach was quite angry at half-time," conceded star forward Donyell Malen. Will he be a bit cheerier at full time in Granada?
Worth pointing out
• Rangers' Kemar Roofe scored from halfway when his side took on Standard Liège on Matchday 1, and made his mark with another terrific strike as the Glaswegians drew 2-2 with Benfica last time out.
• Gareth Bale made the first start of his second spell with Tottenham when Spurs played upcoming opponents LASK on Matchday 1. Carlos Vinícius got his first Spurs goals in the 4-0 win against Ludogorets last time out; is it Bale's turn now to notch his first UEFA Europa League goal since returning from Real Madrid?
• LOSC's Yusuf Yazıcı remains the form player in the UEFA Europa League according to the FedEx Performance Zone, as well as its six-goal leading scorer. Top fact: the 23-year-old attacker is the first player to hit two away hat-tricks in a single season in a major UEFA club competition.
• Munas Dabbur remains on course to become the overall top group-stage scorer in UEFA Europa League history as Group L leaders Hoffenheim visit Crvena zvezda. With 18 goals – including four this term – the Israel striker is level with ex-Athletic Club forward Aritz Aduriz at the top of the table.
• Villarreal need one more goal to surpass Salzburg and become the all-time UEFA Europa League group-stage top scorers. If they avoid defeat at Sivasspor, the Yellow Submarine will also be sure of making it a tenth qualification from ten UEFA Cup and Europa League group stage campaigns.
