Paul Merson has questioned whether Chelsea's deadline day signings are "good enough" to take the team forward, raising concerns over whether Antonio Conte panicked himself into making the wrong decision.
Chelsea were one of the most active Premier League clubs on the final day of the window, signing Marcos Alonso from Fiorentina in a £23million deal and, more shockingly, David Luiz from PSG for £30m.
The Blues had searched far and wide for a new centre-back for most of the window and it seems Luiz, who originally left Stamford Bridge for the French capital in 2014, was way down on their list of potential signings.
Some critics have suggested that Luiz will bring character and leadership to a Chelsea team that otherwise lacks it. Indeed, while John Terry remains captain, his standing amongst a wave of new signings has diminished from what it once was while the personalities of Didier Drogba and Frank Lampard have yet to be replaced.
There is also relief that Chelsea have finally signed a left-footed left-back after years of forcing Cesar Azpilicueta to play out of his natural right-sided position. But as it stands, there are far more concerns with the £53m double purchase than there is confidence. Much of that angst appears to be coming from Merson.
Merson pointed to Luiz's final performance in a PSG shirt, in which he gave away a penalty. His performance was later marked as a 2/10 by L'Equipe and he suggests the French club were delighted to get the chance to cash in, even for a significant loss.
"I don't think Marcos Alonso is good enough for Chelsea," he wrote on Sky Sports.
"David Luiz? No, no, no, no, no. Did you watch him play against Monaco last week? He gave away the silliest penalty I've ever seen and Paris Saint-Germain probably dropped him off."
Despite claiming Conte has just chucked away a load of Roman Abramovich's money on sub-par players, Merson still awarded Chelsea an A+ for their summer transfer business based on the arrival of Michy Batshuayi and N'Golo Kante.
He continued: "Michy Batshuayi looks lively so far, and N'Golo Kante makes Chelsea the team to beat this season. I'm still giving them an A+ because I think Kante is that good."
Spending an estimated £120m in the transfer window, Chelsea were the third biggest spenders behind Manchester United (£160m) and Manchester City (£165m) but having finished tenth in the Premier League last season, they have much more catching up to do than their title rivals.
There is also much to be said of Conte's ability to keep his best players despite the absence of European football. Diego Costa and Thibaut Courtois were both reportedly looking to leave but were convinced to stay by the Italian manager. That in itself is a noteworthy achievement.
