With the two-week Madrid Open reaching halfway, this is the perfect time to revisit the tough problems of tennis.

Expanded several ATP and WTA tournaments in two weeks, causing some controversy - which is controversial.

The idea is that slim events will have a greater appeal – basically creating a “mini grand slam.”

According to ATP and WTA bosses, this means adding more financial opportunities to the players.

Another benefit is that players take a few days off between matches, theoretically, better recovery and more high-quality matches can be played.

In turn, fans will be more involved and media coverage will increase, just like the four existing majors, causing a sensation around them.

For many, it is not eliminated like that.

The players are of course divided. When asked what they like, both Aryna Sabalenka and Iga Swiatek responded positively in Madrid.

Sabalenka said she likes longer formats because she can "rest" physically and mentally between matches, while Swiatek added that she no longer "consider".

But the top stars – people who often go deep into these draws – players are more likely to benefit from the rest days.

Others raised concerns.

A recent lawsuit filed by the Professional Tennis Players Association (claiming to represent the entire player population") says, “rather than providing professional tennis players with more rest between games to endure longer seasons, ATP and WTA give them less.

It also tells him that Novak Djokovic, who co-founded PTPA, gave a long answer at his PRID press conference.

When asked about Carlos Alcaraz saying he felt like a "slave" of the game, Djokovic mentioned the negative effects of the expansion incident.

"Now, we essentially don't have four Grand Slams - we probably have 12 Grand Slams. A lot of them," he said.

Now, seven of the nine ATP Masters play in two weeks, with 10 WTAs 1,000 times.

The first week of the Madrid Open - a mixture of qualifying and main draw - felt like a slow burner.

Caja Magica's main stadium is rarely filled, although the venue is swelled by hundreds of children on school trips.

For many people in the distance, disconnected arrangements seem illogical and difficult to follow.

Any changes?

ATP Chairman Andrea Gaudenzi is committed to the format, and while the WTA insists that the Tour is always under review, its chairman Steve Simon also believes the structure will not increase the workload.

As Swiatek basically says, it seems everyone has to keep moving forward.
