The 18-year-old has made 27 appearances for the U18's but is yet to feature for the U23's with Marc Bola the preferred choice for the reserves so it's interesting that Emery invited Thompson to train with the first team squad this afternoon ahead of the Vorskla game.
"The first three months with Ivan were very important for me because he's a big person, and a professional person too", said Emery.
In 2000, Arsenal played the final against Galatasaray but didn't win.
Cech has started all five league games so far despite struggling at times to cope with Emery's style of play, which dictates that the goalkeeper takes an active part in the passing game when building from the back.
"He is in the starting line-up after we have spoken with Javi Garcia, the goalkeeping coach", Emery confirmed. "We are going to change some players because we need to give some players minutes". I am very happy with his every work day and I am looking forward to him playing well.
Emery will use the game to blood some of his fringe players but is keen to do well in the Europa League to mend a hole in Arsenal's history under Arsene Wenger. Arsenal's chief executive was pivotal in appointing Emery in May, but the Spaniard says he respects Gazidis's decision to leave.
"In my career, the ambition is very important for continuing to improve and continuing to achieve the objectives in my career personally and with the team".
I imagine there will be a lot of changes with the likes of Alex Iwobi and Henrikh Mkhitaryan coming in, so it will still be a strong enough team for me to expect Arsenal to win this.
Arsenal were the losing semi-finalists in the Europa League previous year, but Vorskla Poltava manager Vasyl Sachko says his side are capable of getting a win.
Unai Emery is well versed in the European competition after winning it three times in a row with Sevilla.
Stephan Lichtsteiner admitted: "To come back to the glamour games you need to win first the other games".
"Arsenal are not a Europa League team, they are a Champions League team". It is a long way.
