Chelsea are staring down the barrel of what talkSPORT host Andy Jacobs calls "the biggest decision in the club's history" this summer—and he warns that getting it wrong could see them follow in Tottenham's footsteps.

It's been another turbulent season at Stamford Bridge. The Blues sit ninth in the Premier League with just three games remaining, having lost six consecutive league matches while scoring only once during that stretch. Monday's 3-1 defeat to Nottingham Forest was the latest blow in a campaign that has left fans frustrated and searching for answers.

There's still an FA Cup final against Manchester City on the horizon—a chance to salvage some silverware from a disappointing season. But Champions League qualification looks like a long shot, relying on a sixth-place finish and Aston Villa finishing fifth while winning the Europa League.

This summer looms as a pivotal moment for Chelsea. The club needs to appoint a new head coach and bring in serious reinforcements. But Jacobs is sounding the alarm, pointing to the short-lived tenure of Liam Rosenior—who lasted less than four months—as a cautionary tale.

"People are having a go at the players, but it's like the Spurs players under Igor Tudor—it's not them, it's the manager," Jacobs told talkSPORT. "The manager does matter, who it is, and the whole structure. This season's over and it's done. Now it's the biggest decision in the club's history—they've got to get it right. If they don't, then everybody can see the writing on the wall and what's going to happen next season."

Despite reports linking Chelsea to Barcelona legend Xavi Hernandez, there's been no official confirmation of contact. For a club that prides itself on ambition and success, the stakes have never been higher. The right hire could reignite the Blues' fortunes—the wrong one could set them back for years.
