SAN JOSE — The Earthquakes opened training camp Tuesday with a lot of missing pieces heading into the 2017 Major League Soccer season that is supposed to mark a major shift for the floundering club.

But new general manager Jesse Fioranelli said everything could change by summer for a playoff push during the second-half of the season.

“The winter transfer period produces a limited amount of good opportunities,” Fioranelli said of the Earthquakes’ search to rebuild the roster. “In the summer there will be more options where we can strike a deal that gives us not only more support on the field but also a player that will want to commit long-term to the Earthquakes.”

The summer transfer window when players are available to sign with new clubs is July 10-Aug. 9.

“There will be a second part of the season where we can attack after we have already sent a strong message on the field in the first months of the season,” Fioranelli said.

But the Quakes are a work in progress before the season opener March 4 at Avaya Stadium against the Montreal Impact because they have too many holes to be considered a serious threat.

Instead of restocking completely, San Jose officials seem content to make one more major signing in the coming days to boost the team’s chances to end a four-year playoff drought. Fioranelli expects to make an announcement within 10 days.

“And I look forward to surprising many people,” said the team’s new leader who has worked in Italy’s Serie A before joining MLS.

The latest report — from Fox Sports Netherlands — has Dutch forward Danny Hoesen, 26, agreeing to a deal to play in San Jose. He is owned by FC Groningen of Holland’s top league. Hoesen presumably wouldn’t arrive until after the international transfer window opens Feb. 14.

The report quoted FC Groningen’s general director Hans Nijland stating that they are in the final stages of completing the Hoesen deal.

Fioranelli didn’t dismiss the report, which he claimed he hadn’t read.

“I didn’t hear it yet, but if he said so, he has a lot of credibility,” Fioranelli said of Nijland. “I can’t comment on it yet because it is not official yet.”

Quakes coach Dominic Kinnear declined to discuss Hoesen — or any other rumored signings — because the players are under contract with their respective clubs. But the coach praised Hosen, saying, “He’s played in Holland and he’s a capable player.”

According to other media reports, Albanian winger Jahmir Hyka also might be joining the team. Hyka, who plays for FC Luzern of the Swiss Super League, might not be available until the summer transfer window. That would line up with Fioranelli’s statement about making bigger moves this summer.

However, ESPN FC has reported that the Quakes no longer are pursuing Club America striker Darwin Quintero, a naturalized Mexican citizen from Colombia who was originally thought to be San Jose’s top target.

While training day opened with questions about signings, it also underscored how threadbare the roster is six weeks before opening day. All-Stars Chris Wondolowski and David Bingham, and Darwin Ceren (El Salvador) and Harold Cummings (Panama) are training with their respective national teams after getting called to international duty.

They will return before the season begins.
