Manchester United legend Rio Ferdinand wants Chelsea boss Frank Lampard to make two signings this summer.

Ferdinand was speaking after the Blues lost 4-1 to Bayern Munich on Saturday, and 7-1 on aggregate.

After the humbling round of 16 Champions League defeat, Ferdinand said Lampard must target a centre-back and goalkeeper.

Ferdinand told BT Sport: "I think Frank's done his work early, that's good business [signing Werner and Ziyech].

"The players he's brought in are players that can play and know the level at Champions League football. I think they're an upgrade on some of the players he's got.

"Definitely adds competition, but I think now he has to look at the other end of the pitch because that's an area that when you want to win things, big trophies, which Frank will be wanting to do.

"That's the demands of that club, the foundations in the centre-half area, goalkeeper have to be strong."
