They are now set to be joined at Anfield by Croatia international Lovren, who is expected to be announced as a Liverpool player on Monday.
The outspoken 25-year-old has made no secret of his desire to leave the club he joined from Lyon last summer, moving for a deal Press Association Sport understands to be worth £20million.
