Group E surprised us, Romania managed to finish in first place beating Belgium which on paper could be much better. Maybe facing the Netherlands is not easy, it's just that in terms of opportunities, Romania still has the strength to put up a fierce fight, the round of 16 is definitely a strong reason for Romania to play at full strength.
Slovakia is not a top team that can progress further, England should be able to handle this well but even that is not 100% if you look at England game which always has difficulty finding the ideal formation. Southgate is considered a rubbish coach who is unable to utilize his star squad.
Compared to Belgium, which will face France in the round of 16, I think Romania is a little lucky against the Netherlands in the round of 16, even though it is equally difficult, Romania still has the percentage to be able to beat the Netherlands in the round of 16.
In the Group E phase it was quite fierce and I think Romania's success in becoming the leader of the standings was because Belgium did not perform well at this Euro.
France round of 16 match against Belgium will a tough match and for Lukaku who will have to be as destructive as mbape in the attack, it's a huge responsibility he has on his shoulder to put out a good performance considering the stage they've gotten to where a draw is not what they need. They have a solid and well experienced three man attack which is coming from doku, Kelvin de Byrne and lukaku and if they have learnt the necessary lesson from thier lapses at the group stage in terms of thier inability to converting most of the opportunities they've hard and are ready to do better in this round, then they can shrink all the efforr mbape will come with but if they still play like they are in the group stage, France will certainly suck them dry.
In the group phase, England have not shown an impressive performance, but I don't think they will have any difficulties in the round of 16 against Slovakia.
And what happened in the group phase cannot be used as a reference, there is still a big possibility for England to improve their performance if you look at the squad they have.
England has all that it takes not just to win Slovenia but to get to the finals of the Euro but that's only going to be a reality if the coach is ready to change is tactics that's not working and try out something different that will work well for him. The fact that Bellingham is still starting all the matches and players complete 90 minutes is part of what needs to be check in this round or Slovenia would drag them to a draw and head to the penalties with them. If he tries kubo maino and Cole Palmer out in there next encounter, you're already sure that the result is going to be a favourable one in thier favour but anything below that is a sure sign that if they manage to play well, they might just see themselves getting into penalties in this match.
