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.
