Derby County boss, Frank Lampard said Efe Ambrose will bring competition and experience to the English Championship side, just as the match fitness of the Super Eagles defender would also be assessed this week.
“Efe brings experience of playing at Celtic, many games, and Hibernian and playing internationally,” said Lampard.
The Chelsea legend also said Ambrose would be assessed this week to determine his fitness for games.
“Efe will have to be assessed at the start of next week,” the Derby County manager said.
“There was certainly an issue with match fitness, as there has been with Ashley Cole, none of their own fault. Ashley was out of season, and Efe was out of contract.
“Whatever you do in that situation does not equate to training and be prepared to play a match.
“My feeling is he (Ambrose) is a week or two away from being in the squad.”
