Chelsea are making a late move for Lazio midfielder Felipe Anderson.
Calciomercato.com says West Ham and Chelsea are facing off against each other and European giants Monaco and Valencia in the battle for Anderson.
The Hammers had appeared on the brink of confirming a €40million move last month, but Lazio upped their valuation to €50m.
The Italian side insist they don't need to sell with all four sides set for a bidding war.
For his part, Anderson has told Lazio president Claudio Lotito he wishes to join West Ham.
