SAINTS boss Russell Martin claimed nothing phases Alex McCarthy after the goalkeeper's "massive" performance at West Brom.

The 34 year old produced two top-class saves to deny Grady Diangana what would have been a winning goal at the Hawthorns.

McCarthy's exploits ensured Southampton will take a 0-0 draw into the second leg of their playoff semi-final against the Baggies.

The former England keeper played a bit part role under Martin until first-choice shot-stopper Gavin Bazunu's season was ended by injury.

Asked for his verdict on McCarthy's performances since he returned to the starting lineup, Martin said: "He's been great.

"He was massive today, (he has great with) long throws and the way he came and dealt with things. The last two weeks I’ve loved the way we’ve defended.

"I just don't think anything phases him. He has that laid-back mentality but he really backs himself as a goalkeeper. 

"He has been fantastic."

The two-time England international was voted player of the match by Southampton supporters after his heroics between the sticks.

Teammate Flynn Downes described McCarthy as a "joke" before adding: "It's a privilege to play with him."

A number of Saints supporters took to social media on Sunday to give the veteran goalkeeper his flowers.

Glen de la Cour wrote: "Nice to see the 2017 Alex McCarthy turn up today. Excellent performance."

Martin Bellis added: "Gotta say that once again he was superb. Great professional performance today. He made sure we didn’t lose, job done! C'mon The Saints."

@SaintsDanSFC said: "We have all doubted Alex McCarthy, including myself. However, he stood up when it really mattered."

Mitchell Symonds claimed: "Alex McCarthy was mustard today, that may be the best game I’ve seen him have for us."
