Sevilla was taking a very fast decision to sack him and i would be so doubtful to think that if sevilla will have big chance to win against manchester united. Sevilla needs to find a new coach as soon as possible before the match against MU. I would not be surprised to see that sevilla to see sevilla lose against united since when sevilla will have a new coach and there will be new rules, playstyle that needs to be adapted by whole of players in the club.
The thing that must be the main concern is about how bad the attacking lines that owned by sevilla. Sampaoli already sacked by club. Club is trying to find a new name as replacement for his spot.
The new coach will have very big pressures and i think that if it's quite hard to find a new guy that will be willing to handle the club to get big pressure instantly.
Without any doubt this is big blunder from the management of Sevilla because sacking of Sampaoli is not going to help them at this stage of season while they are in quarter-final of the Europa Cup and still have plenty of done in last few rounds of the La Liga which can hurt their cause and also can bring down teams performance as well with they are already down and have no enough chances for the survival into both competition going to face team like Manchester United and having not solid strategy is surely the worst thing happened just like we have in Chelsea few months back.
Their performance in La Liga was also improving, but they lost heir patience after lost against Getafe so management done this big mistake and now most chances they will also face consequences for this as well in April when their team will be out of the Europa Cup.
