Chelsea just reacted strongly after the defeat to Arsenal with a 4-1 victory at Villa Park. Joao Pedro scored a hat-trick, and Cole Palmer also wrote his name on the scoreboard in the impressive performance of Liam Rosenior's team.
Collymore was particularly impressed with The Blues' performance at Villa Park: "I think Chelsea's performance the night before at Villa Park was excellent. It was the best performance of a team at Villa Park in years.
The former England striker also appreciated Chelsea's transfer policy: "As for Chelsea, I really think that buying all these players is reckless and crazy, but they have money and a very simple policy - buy the best young players.
Does catching up on speed always take two, three, four years? It's not necessary, some teams catch up very, very quickly.
The former striker also compared Chelsea to last season's European champion - PSG: "They are the team with the most similarity to Paris Saint-Germain, the team that won the UEFA Champions League. They are more like PSG than any other team in England.
I think they should persevere with the principles of cross-field play, fast, creative play, combined with Cole Palmer regaining his form. Maintaining that, they are strong enough to compete for the championship in the coming seasons”.
Collymore also praised the most impressive player in the Chelsea squad. He said: "You can see Alejandro Garnacho on the left wing. In the match against Aston Villa, it was the performance of the best winger I have ever witnessed directly this season.
