Chelsea defender Thiago Silva has voiced his concerns about the club's future and has called for a "strategy" to be put in place to avoid another difficult season.

The club's 11th place finish in the Premier League this season and failure to win a trophy has raised questions about the effectiveness of their £550m investment in new players.

Despite the lavish spending, Chelsea have sacked two managers and currently have an interim boss.

Silva has pointed out that it's difficult for the manager to choose only 11 players out of a squad of 30 and that the team needs to stop and plan for the future to avoid repeating the same mistakes.

Silva also highlighted that there are amazing players within the squad, but there will always be players who are unhappy.

"It's a difficult moment for the club, with a lot of indecision," added 38-year-old Silva.

"We had to increase the size of the changing rooms because it didn't fit the size of the team.

"A positive point is that there are amazing players within the squad, but on the other hand there is always players that are going to be unhappy.

"We need to stop and put a strategy in place, otherwise next season we could make the same mistakes."
