adminhe famously overhauled Arsenal’s Invincibles and led the Blues to consecutive titles.
Mourinho has also been tipped to make Atletico Madrid striker Radamel Falcao his first big signing as he prepares to succeed Rafa Benitez.
Arsenal manager Wenger said: “I’m afraid of what Chelsea can do in the summer. We have to be prepared for them to be one of the biggest movers in terms of investment once the window opens.
“Even though they already have a great base to their squad, notably their young players such as Oscar, Juan Mata, Ramires and Eden Hazard, I think they will be busy during the transfer window.”
The Gunners’ boss added in an interview with Eurosport: “We’ve heard a lot of talk about Radamel Falcao. Some people say it’s already a done deal, but I’ve heard nothing.
“I think Chelsea currently have a great coach in Rafa Benitez, but if they part ways at the end of season, of course Jose Mourinho would be a good solution for Chelsea.
“Mourinho is one of the best in the world. But I consider Benitez to be doing a good job at Stamford Bridge.”
Meanwhile, Arsenal have opened talks with Fiorentina over buying their top striker target, Stevan Jovetic.
Gunners manager Wenger has identified Montenegro international Jovetic as his first-choice big-money buy for this summer.
Italian side Fiorentina are demanding in excess of £20million for Jovetic, and Arsenal are also likely to face stiff competition from Juventus and other Serie A clubs. But the north Londoners are trying to steal a march on their rivals by making this early move and sounding out his representatives.
Jovetic, who played against England in a drawn World Cup qualifier last month is understood to be keen, but any move may depend on Arsenal getting into the Champions League with a top-four finish this season.
Wenger, who has been promised around £70m to spend this summer, was keen on Barcelona striker David Villa but the fact Jovetic is almost eight years younger makes him more attractive than the Spaniard.
Arsenal are looking for a striker to compliment Olivier Giroud and give them a different option, and Jovetic fits the bill. — Mailonline.
