The draw will be today, so soon we will know all the opponents in all groups. It's funny to see Newcastle in the fourth pot, apparently the group where Newcastle gets will be one of the most difficult. Actually, it's not worth guessing now, we just need to wait until the evening and we will know what the Champions League groups will be like this year. By the way, Sevilla is just as strange to see the first group, especially considering how they started their season in La Liga.
Newcatsle United got an amazing past season which brings them to Champions League this season, but it is their first appearance there after many years. By that, Newcastle United are stepping similarly like Manchester City years ago. By starting in Pot 4, they will face with risk of falling in very tough group and meet very strong opponents from other leagues. It takes Manchester City a few seasons to improve their perform in Champions League before more stably appear in knock-out phase.
Sevilla will likely to drop from Champions League to Europa League again as with their super poor performances in La Liga, I have no belief that they will be able to complete group stage well to go to a first knock out phase.
if we talk about Barcelona chances in the UCL it will be difficult after the financial woes from last season which caused Barcelona to find it difficult to bring in quality players or talented players. Im not saying that Barcelona does not have top players, but its impossible if Barcelona only relies on Lewandowski while the defense also needs high quality players.
They are on their ways to improve, first improving in La Liga two seasons ago, won it in the past season. We can expect them to repeat such improvement in Champions League. They were deranked to Europa League last season so let's hope they will not be deranked after the group stage and even can go a bit far in knock out phases.
