The partnership, which starts 1 July and runs for three years, will also feature the snacking giant's Doritos, Lipton and 7UP brands - though PepsiCo is yet to reveal details of its sponsorship programme.
"With more than a billion football fans watching the matches every season, this new partnership offers unprecedented opportunities for both parties," said Ramon Laguarta, PepsiCo Europe CEO.
"UEFA Champions League fans can expect some fantastic new experiences from Lay’s, Gatorade and Pepsi MAX as we head into the 2015/16 season," he added.
