Well I think she should definitely add a tournament into the Wimbledon schedule.
Serena needs the match-tightness that comes from winning in these tight moment.
She's got to put herself in the best situation.
I just want her to bring the Serena that we know is there.
She just looked really tight out there.

The 21 year old has knocked out the 39 year old.
Elena Rybakina knocks out 23-time Slam champion, in straight sets too.
Serena just shakes her head.
Rybakina 6-3 7-5 S Williams
Serena Williams falls in the last 16 of the French Open.
Elena Rybakina is as cool as a cucumber, reacting to the final point by trotting to the net and then acknowleging the sparse crowd with a little raise of her racquet.
She plans to be seeing plenty more of the showpiece stage over the next week.
*Rybakina 6-3 6-5 S Williams
That did not look promising for Elena Rybakina.
The Kazakh chops an awkward forehand wide in the opening point of the game.
Better as she nibbles back to 30-15.
And then two match points as Serena smears long under little pressure.
Russell Fuller
BBC tennis correspondent at Roland Garros
Serena's been in these tight situations so many times in her career, but obviously not as recently.
Rybakina has the chance to serve out the match and knock out Serena Williams.
What is she thinking?
*Rybakina 6-3 6-5 S Williams
Serena dumps a backhand into the bottom of the net with a tired heave of the shoulders.
She is backed up to the brickwork. Elena Rybakina to serve for the biggest win of her young career next...
Rybakina 6-3 5-5 *S Williams
Elena Rybakina hits her own turbo boost button.
Two massive winners, a Serena double fault and she has three break points.
Take one and she will serve for the match...
Rybakina 6-3 5-5 *S Williams
The tightrope is getting skinny and slippy. Not a milimetre left for Serena Williams to make an error now.
Elena Rybakina holds serve to take us right into the pointy end of the second set.
Laura Robson
Former British number one on BBC Radio 5 Live Sports Extra
She's just about doing enough but it's tough going for Serena Williams.
You can see she's just going to have to work through these tough moments.
*Rybakina 6-3 4-5 S Williams
Oh wow.
Serena Williams makes a horrible hash of the first point but lands a backhand plum on the line to pull the game back to 15-15.
It is either sensational or shocking from her at the moment.
Elena Rybakina reminds everyone that she will have a say in how it all pans out with a fine forehand down the line for 30-30.
But it is Williams' game....

Alexis is applauding loud and long in the stands. Serena has stayed in the fight and pulled the second set back on serve.
Laura Robson
Former British number one on BBC Radio 5 Live Sports Extra
This is where we will start to see the pressure creep in to Rybakina's game.
That was a bit of a gift.
Well - that was nervous from both players, I think!
*Rybakina 6-3 4-3 S Williams
Elena Rybakina tugs a forehand down the line into the top of the net to give Serena Williams a look at 15-30.
But a kicking wide serve stretched Serena all out of shape for 30-30.
Rybakina boffs a nothing much shot long to offer up break point.
Laura Robson
Former British number one on BBC Radio 5 Live Sports Extra
I don't think Serena has been consistent enough from the back of the court, and I don't think she has figured out where to hit.
She looks so annoyed with how things are going
