Many people might expect Lazio to win the match because they were playing at home and likely had an advantage over Udinese, but if we look at the results of both team's previous games, you might doubt Lazio's winning. Udinese dominated the game and deserved to win; they had 15 shots, 4 were on target, and 51 ball possession, while Lazio had 10 shots, 5 were on target. Perhaps Lazio did not put up much effort in this game because of their next Europa League game, that might be a chance for them to win a title this season.
The Lazio performances be in the series A people where think that they?re not serious they don?t know that all their planed is against the Europa League, because they want make sure that they dominate the Europa League this season; and that?s why we can see their performance is very powerful in the league than the series A. Because they understand that even thought they put in efforts in the series A they might know go any where, since they?ve left behind already is more better for them to hold the Europa league very strong where their leading the top of the table with the highest points.
There is no conclusion drawn from the results of the match because Udinese is a team that has good quality this season especially in the last few matches Udinese's performance has continued to improve so even though Lazio played at home of course it was not easy for them to beat Udinese so a draw is a fairly fair result for both teams.
Udinese is now in the middle of the table, they just started the season a little bad if not they could compete for the top 4 position while Lazio still has a good chance of finishing in the top 4 so with the performance and strength that Lazio has I think they have everything to be able to compete fiercely for the top 4 position.
Lazio, as you said, will rightly fight to finish fourth in the league, they can do it, I consider Juventus a team that can no longer compete even in the league and it is easy that there is a problem and that they cannot finish the season even in the Champions League zone, I think that Roma can also surprise in this final part of the championship, everything will depend on what they do with Bilbao
