I personally don't believe Sheriff Tiraspol will get points in the remaining matches, and maybe the only chance for Sheriff Tiraspol to get points later is against Shakhtar Donetsk, whether it's for 1 point or 3 points. But Shakhtar Donetsk itself is not a new team in UCL so I still believe Shakhtar Donetsk will be able to provide a strong resistance in the second match later against Sheriff Tiraspol. Therefore, maybe Sheriff Tiraspol will be able to lock in the 3rd position because I believe, Madrid and Inter will still fill the 1st and 2nd positions as expected.
Yes, I also feel in this way, but having two matches at home can give them some advantage after having very good start in this season. If they want to go in next round then surely next match is very important for them because this can change all positions and then Sheriff will have some more chance for qualifying for next round if they lost all remaining matches then surely they will be moved into UEFA Europa League because they have already done enough work for playing this League and Shakhtar will be out of this competition. Inter is also having some good results in last matches.
