Ralf Rangnick has claimed Ronaldo 'can still be a big help' to Manchester United going into next season.
There has been speculation over the ex-Real Madrid's future at Old Trafford with Erik ten Hag arriving in July.
Ronaldo's goals in the league for United have proved crucial and without them, the side would be in the bottom half of the table. The 37-year-old was on hand again to earn United a point at Old Trafford against Chelsea.
Ronaldo had a chance to earn the hosts all three points but his effort was saved by Edouard Mendy.
Rangnick was impressed by the 37-year-old's performance alongside some key saves made by David de Gea.
"We showed a good reaction in the second half, and it was a great finish from Cristiano Ronaldo. In the first half we had our problems and we needed a few great saves from David de Gea.
"Second half we did better and we got more control. You could see they are a top team, no coincidence they won the Champions League and we don't have much confidence and had eight players missing.
"Although it was still a lucky draw, we earned it. At times we saw the gap, but they played with their best XI and we had players missing.
"We have problems with defending, not compact enough and not physical enough.
"Not only the goal Cristiano scored but his whole performance, his attitude at age of 37, this is not normal to do that. If he plays like he did today he can still be a big help to this team.
"It is Erik's and Cristiano's decision for what he can do next but today his performance was really great."
