Great Britain have moved one match away from winning the Davis Cup after Andy Murray and Jamie Murray won in four sets against David Goffin and Steve Darcis.

After the opening two sets were shared, the two Scottish brothers held their nerve to run out 6-4 4-6 6-3 6-2 victors in Ghent to give Leon Smith's team a 2-1 lead ahead of Sunday's reverse singles.

The opening set was tightly contested, with neither side creating a break point until the ninth game, but after Great Britain saved it, they struck in the next game to move into a one-set advantage.

However, Belgium, spurred on by their passionate home following, broke early in the second and that proved enough for the hosts to get the rubber back on level terms.

Belgium also broke early at the beginning of the third, but two successive breaks of serve for Great Britain put them 4-2 up in the set, only for Jamie Murray to lose his own serve for the second time in a row.

The trend continued in the eighth game as Great Britain moved into a 5-3 lead, before Andy Murray served the set out to put his team one away from victory.

Great Britain got the break during the early stages of the fourth, but Jamie Murray played an equally crucial role in saving seven break points in the same service game to open up a 3-1 advantage.

The visitors broke again in the seventh game to give them two games behind their own delivery to serve the contest out, but they only required one as Jamie Murray came through to 30, much to the delight of the travelling British support.
