Chelsea have been linked with the duo of Bundesliga strikers Robert Lewandowski and Alexander Isak according to a report in the Mirror.
The Blues are in the market for a prolific presence at the top and Lewandowski and Isak are said to fit the bill.
Lewandowski,30, has already established himself as one of the most prolific goal scorers in Europe but his high asking price along with his age could render the Blues reluctant to complete the deal.
Isak,19, on the other hand, is a low profile striker plying his trade with Dutch club Willem II where he has scored 11 goals in 11 appearances on loan from Bayern’s arch-rivals Borussia Dortmund.
All this speculation could go down in vain if CAS does not overturn FIFA’s currently imposed two-window transfer ban on Chelsea.
