Frank Lampard will face a Champions League headache if, as expected, he succeeds Maurizio Sarri as Chelsea head coach.

Chelsea are preparing for the fact they will start serving their two-window transfer ban this summer, which will prevent the club from making any new signings.

That has removed the need to rush into appointing Lampard, with the Blues not currently active in the transfer market and the next head coach having to work with the current squad, who return for pre-season training in the first week of July.

But it leaves the Blues a problem over the make-up over their Champions League squad for next season.

The departures of captain Gary Cahill and midfielder Cesc Fabregas over the past six months mean Chelsea cannot fill their home-grown quota with first-team players.
