Inter are a joke. How a club with many good players can't take a single point against Beer Sheva, conceding five goals? If they want to react and make a step forward, they should sack the board, the manager (because isn't good for a club who wants to qualify for the Champions League) and many players, starting with Jeison Murillo (he was good in Spain but he is totally awful in Italy) and Mauro Icardi.
Better then them, there are Zenith (I'm still a fan of Kokorin), Ajax (many young players from the U19, today. They are a joy to watch under Peter Bosz), Shaktar (Dudu is still in business ) and Schalke.
United (because they have a great squad for the Europe League), Zenith and Ajax are my personal favourites to reach the semifinals, plus the squad from the CL who will join them (Napoli or Benfica, PSV if they will beat Rostov).
