Servilla has a good record against Manchester united in the past. I don't know what was wrong with those matches but all I know is that ten Hag boys need to learn from the mistakes made from those matches in order to secure themselves against any outcome.
Manchester United is in a good form, thanks to Ten Hag who has set the system to this level, but it will add more to Ten hag record if he get the Europa league this season. I'm sure he knows this.
Didn't their last meeting take place several years ago, in 2020 to be precise? When compared to 2020 and this year especially after Ten Haag took over from Manchester United as coach there the difference is already very big and Manchester United are already in very good development at the moment so the previous H2H is unlikely to affect this match at all.
Sevilla must be very careful when dealing with Man United, the first or second leg will not give them a big advantage, because that was clearly seen when their opponent managed to hold Barcelona at the Nou Camp in the previous round, and finally beat Barca at Old Trafford, even though Barca is far more favored than United and also Barca is in relatively better condition than Sevilla, which is still outside the top 10 in the league until now. Man United are far superior to reach the semifinals and that could fail if their main player is injured or something else so he can't play for United, as long as all of Ten Haag's pillars are playing and fit then United will be difficult to contain by Sevilla.
