The 42-year-old American had not played on the tour since last August but requested a late entry to play with two-time winner Murray as she aims to win the mixed competition at the All England Club for the first time. Murray is a five-time mixed and two-time men's doubles major champion, while Williams has won 14 women's doubles Slam titles alongside sister Serena in addition to two mixed doubles triumphs. Wildcards Murray and Williams, who in all boast 23 Grand Slam doubles titles between them, overcame Michael Venus and Alicja Rosolska 6-3 6-7 (3-7) 6-3 in their first-round match. If you're not in a long-term partnership, someone else could come along and a player will think 'they're better, so I'll ditch my current partner'. It's definitely an important thing to get on well with the person,' he added. 'I used to think it wasn't that big of a deal because you can just focus on the tennis and not spend time with them off the court but it doesn't really work like that. 'I've definitely had partners where it just hasn't worked out personality wise.

'I have had some bad experiences,' said the Briton. It's the sort of uncomfortable situation that men's world number one doubles player Joe Salisbury knows all about. Tan's recovery in time to defeat Sara Sorribes Tormo a day later has certainly not helped reconcile their fragile relationship.

Just ask German Tamara Korpatsch, who was left 'sad, disappointed and also very angry' after proposed partner Harmony Tan pulled out last-minute following her singles win over American great Serena Williams.
