A lot has been made about Liverpool's lack of spending in the transfer window. 

The Premier League champions have made just one signing of note - Konstantinos Tsimikas - and he's expected to be nothing more than a squad player for now. 

Despite a lack of activity, the Reds did win their first game of the new campaign, beating newly-promoted Leeds United 4-3 at Anfield. 

However, Sky Sports pundit Paul Merson believes their opening-day win threw up more questions than answers.

In fact, he claims that Liverpool are in danger of finishing as low as fourth this season and believes their poor transfer window could cause serious issues down the line. 

"You look at the goals Liverpool let in against Leeds: wow. I just think they turned up and thought they would wipe the floor with Leeds," Merson said in his Sky Sports column.

"I think they need to buy someone. It would not surprise me if the finished fourth this season, and I thought that before this game. 

Liverpool could struggle to retain their PL crown

"It's the same team, and they have a massive amount of players who have to play every week."

Merson went on to compare Liverpool's lack of spending to a 'famous fast-food chain' that continued to dominate the market because they 'spent to stay at the top'.

"Virgil van Dijk cannot get injured. The full-backs cannot get injured. They have not got anyone to replace the front three if they are injured. 

Liverpool need to keep Van Dijk fit

"I keep saying it. There's a famous fast-food chain that used to sell more chips and burgers than anyone; they still did adverts. You spend to stay at the top."

That's certainly a strange comparison between football and fast-food, but you've got to admit, the Sky pundit has a point. 

While every team around them is moving forward, spending and looking to strengthen, Liverpool risk falling behind their Premier League rivals.

If they fail to get the Thiago deal across the line, they may suffer next season. Fourth-place is a bit extreme though, Merse.
